Some Properties of Generalized Apostol-Type Frobenius–Euler–Fibonacci Polynomials

Abstract

In this paper, by using the Golden Calculus, we introduce the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials and numbers; additionally, we obtain various fundamental identities and properties associated with these polynomials and numbers, such as summation theorems, difference equations, derivative properties, recurrence relations, and more. Subsequently, we present summation formulas, Stirling–Fibonacci numbers of the second kind, and relationships for these polynomials and numbers. Finally, we define the new family of the generalized Apostol-type Frobenius–Euler–Fibonacci matrix and obtain some factorizations of this newly established matrix. Using Mathematica, the computational formulae and graphical representation for the mentioned polynomials are obtained.

1. Introduction

Recently, numerous scholars [1,2,3] have defined and developed methods of generating functions for new families of special polynomials, including Bernoulli, Euler, and Genocchi polynomials. These authors have established the basic properties of these polynomials and have derived a variety of identities using the generating function. Furthermore, by using the partial derivative operator to these generating functions, some derivative formulae and finite combinatorial sums involving the above-mentioned polynomials and numbers have been obtained. These special polynomials also provide the straightforward derivation of various important identities. As a result, numerous experts in number theory and combinatorics have exhaustively studied their properties and obtained a series of interesting results.

For any $u\in \mathbb{C}$, $u\ne 1$ and $\zeta \in \mathbb{R}$, the Apostol-type Frobenius–Euler polynomials ${\mathbb{H}}_w^{\left(\alpha \right)}(\zeta ;u;\lambda )$ of order $\alpha \in \mathbb{C}$ are introduced (see [4,5,6,7]).

$${\left(\frac{1-u}{\lambda e^d-u}\right)}^{\alpha }{e}^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{H}}_w^{\left(\alpha \right)}(\zeta ;u;\lambda )\frac{d^w}{w!},\left|d\right|<\left|ln\left(\frac{\lambda }{u}\right)\right|.$$

(1)

For $\zeta =0$, ${\mathbb{H}}_w^{\left(\alpha \right)}(u;\lambda )={\mathbb{H}}_w^{\left(\alpha \right)}(0;u;\lambda )$ are called the Apostol-type Frobenius–Euler numbers of order $\alpha$. From (1), we known that

$${\mathbb{H}}_w^{\left(\alpha \right)}(\zeta ;u;\lambda )=\sum _{s=0}^w\left({\displaystyle \frac{w}{s}}\right){\mathbb{H}}_s^{\left(\alpha \right)}(u;\lambda ){\zeta }^{w-s},$$

(2)

and

$${\mathbb{H}}_w^{\left(\alpha \right)}(\zeta ;-1;\lambda )={\mathbb{E}}_w^{\left(\alpha \right)}(\zeta ;\lambda ),$$

(3)

where ${\mathbb{E}}_w^{\left(\alpha \right)}(\zeta ;\lambda )$ are the $w^{th}$ Apostol–Euler polynomials of order $\alpha$.

The generalized $\lambda$-Stirling numbers of the second kind $S(w,s;\lambda )$ are given by (see [8])

$$\frac{{(\lambda e^d-1)}^s}{s!}=\sum _{w=0}^{\infty }S(w,s;\lambda )\frac{d^w}{w!},$$

(4)

for $\lambda \in \mathbb{C}$ and $s\in \mathbb{N}=\{0,1,2,\cdots ,\}$, where $\lambda =1$ gives the well-known Stirling numbers of the second kind; these are defined as follows (see [9,10]).

$$\frac{{(e^d-1)}^s}{s!}=\sum _{w=0}^{\infty }S(w,s)\frac{d^w}{w!}.$$

(5)

By referring to (4), the $\lambda$-array type polynomials $S_s^w(\zeta ,\lambda )$ are defined by (see [11])

$$\frac{{(\lambda e^d-1)}^s}{s!}{e}^{\zeta d}=\sum _{w=0}^{\infty }S(w,s;\zeta ;\lambda )\frac{d^w}{w!}.$$

(6)

The Apostol-type Bernoulli polynomials ${\mathbb{B}}_w^{\left(\alpha \right)}(\zeta ;\lambda )$ of order $\alpha$, the Apostol-type Euler polynomials ${\mathbb{E}}_w^{\left(\alpha \right)}(\zeta ;\lambda )$ of order $\alpha$, and the Apostol-type Genocchi polynomials ${\mathbb{G}}_w^{\left(\alpha \right)}(\zeta ;\lambda )$ of order $\alpha$ are defined by (see [8,12]):

$${\left(\frac{d}{\lambda e^d-1}\right)}^{\alpha }{e}^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{B}}_w^{\left(\alpha \right)}(\zeta ;\lambda )\frac{d^w}{w!}\left(\mid d+log\lambda \mid <2\pi \right),$$

(7)

$${\left(\frac{2}{\lambda e^d+1}\right)}^{\alpha }{e}^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{E}}_w^{\left(\alpha \right)}(\zeta ;\lambda )\frac{d^w}{w!}\left(\mid d+log\lambda \mid <\pi \right)$$

(8)

and

$${\left(\frac{2d}{\lambda e^d+1}\right)}^{\alpha }{e}^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{G}}_w^{\left(\alpha \right)}(\zeta ;\lambda )\frac{d^w}{w!},\left(\mid d+log\lambda \mid <\pi \right),$$

(9)

respectively.

Clearly, we have

$${\mathbb{B}}_w^{\left(\alpha \right)}\left(\lambda \right)={\mathbb{B}}_w^{\left(\alpha \right)}(0;\lambda ),{\mathbb{E}}_w^{\left(\alpha \right)}\left(\lambda \right)={\mathbb{E}}_w^{\left(\alpha \right)}(0;\lambda ),{\mathbb{G}}_w^{\left(\alpha \right)}\left(\lambda \right)={\mathbb{G}}_w^{\left(\alpha \right)}(0;\lambda ).$$

The subject of Golden Calculus (or F-calculus) emerged in the nineteenth century due to its wide-ranging applications in fields such as mathematics, physics, and engineering. The $\psi$-extended finite operator calculus of Rota was studied by A.K. Kwaśniewski [13]. Krot [14] defined and studied F-calculus and gave some properties of these calculus types. Pashaev and Nalci [15] dealt extensively with the Golden Calculus and obtained many properties and used these concepts especially in the field of mathematical physics. The definitions and notation of Golden Calculus (or F-calculus) are taken from [15,16,17,18].

The Fibonacci sequence is defined by the following recurrence relation:

$$F_w=F_{w-1}+F_{w-2},w\ge 2$$

where $F_0=0$, $F_1=1$. Fibonacci numbers can be expressed explicitly as

$$F_w=\frac{{\varphi }^w-{\psi }^w}{\varphi -\psi },$$

where $\varphi =\frac{1+\sqrt{5}}{2}$ and $\psi =\frac{1-\sqrt{5}}{2}$. $\varphi \approx 16180339\cdots$ is called Golden ratio. The Golden ratio is a frequently occurring number in many branches of science and mathematics. Pashaev and Nalci [15] have thoroughly studied the miscellaneous properties of Golden Calculus. Additional references include Pashaev [18], Krot [14], and Pashaev and Ozvatan [19].

The F-factorial was defined as follows:

$$F_1{F}_2{F}_3\cdots F_w=F_w!,$$

(10)

where $F_0!=1$. The binomial theorem for the F-analogues (or the Golden binomial theorem) are given by

$${(\zeta +\eta )}^w:={(\zeta +\eta )}_F^w=\sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{(-1)}^{\left(\genfrac{}{}{0pt}{}{l}{2}\right)}{\zeta }^{w-l}{\eta }^l,$$

(11)

in terms of the Golden binomial coefficients, referred to as Fibonomials

$${\left(\genfrac{}{}{0pt}{}{w}{l}\right)}_F=\frac{F_w!}{F_{w-l!}{F}_l!},$$

with w and l being non-negative integers, $w\ge l$. The Fibonomial coefficients have following identity:

$${\left(\genfrac{}{}{0pt}{}{w}{l}\right)}_F{\left(\genfrac{}{}{0pt}{}{l}{m}\right)}_F={\left(\genfrac{}{}{0pt}{}{w}{m}\right)}_F{\left(\genfrac{}{}{0pt}{}{w-m}{l-m}\right)}_F.$$

(12)

The F-derivative is introduced as follows:

$$\frac{{\partial }_F}{{\partial }_F\zeta }\left(f\left(\zeta \right)\right)=\frac{f\left(\varphi \zeta \right)-f\left(\psi \zeta \right)}{(\varphi -\psi )\zeta }.$$

(13)

respectively. The first and second types of Golden exponential functions are defined as

$$e_F\left(\zeta \right)=\sum _{w=0}^{\infty }\frac{{\left(\zeta \right)}_F^w}{F_w!},$$

(14)

$$E_F\left(\zeta \right)=\sum _{w=0}^{\infty }{(-1)}^{\left(\genfrac{}{}{0pt}{}{w}{2}\right)}\frac{{\left(\zeta \right)}_F^w}{F_w!}.$$

(15)

Briefly, we use the following notations throughout the paper

$$e_F\left(\zeta \right)=\sum _{w=0}^{\infty }\frac{{\zeta }^w}{F_w!}$$

and

$$E_F\left(\zeta \right)=\sum _{w=0}^{\infty }{(-1)}^{\left(\genfrac{}{}{0pt}{}{w}{2}\right)}\frac{{\zeta }^w}{F_w!}.$$

$e_F\left(\zeta \right)$ and $E_F\left(\zeta \right)$ satisfy the following identity (see [17]).

$$e_F^{\zeta }{E}_F^{\eta }=e_F^{(\zeta +\eta )F}.$$

(16)

The Apostol-type Bernoulli–Fibonacci polynomials ${\mathbb{B}}_{w,F}^{\left(\alpha \right)}(\zeta ;\lambda )$ of order $\alpha$, the Apostol-type Euler–Fibonacci polynomials ${\mathbb{E}}_{w,F}^{\left(\alpha \right)}(\zeta ;\lambda )$ of order $\alpha$ and the Apostol-type Genocchi–Fibonacci polynomials ${\mathbb{G}}_{w,F}^{\left(\alpha \right)}(\zeta ;\lambda )$ of order $\alpha$ are defined by (see [20,21,22]):

$${\left(\frac{d}{\lambda e_F^d-1}\right)}^{\alpha }{e}_F^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{B}}_{w,F}^{\left(\alpha \right)}(\zeta ;\lambda )\frac{d^w}{F_w!},$$

(17)

$${\left(\frac{2}{\lambda e_F^d+1}\right)}^{\alpha }{e}_F^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{E}}_{w,F}^{\left(\alpha \right)}(\zeta ;\lambda )\frac{d^w}{F_w!}$$

(18)

and

$${\left(\frac{2d}{\lambda e_F^d+1}\right)}^{\alpha }{e}_F^{\zeta d}=\sum _{w=0}^{\infty }{\mathbb{G}}_{w,F}^{\left(\alpha \right)}(\zeta ;\lambda )\frac{d^w}{F_w!},$$

(19)

respectively.

Clearly, we have

$${\mathbb{B}}_{w,F}^{\left(\alpha \right)}\left(\lambda \right)={\mathbb{B}}_{w,F}^{\left(\alpha \right)}(0;\lambda ),{\mathbb{E}}_{w,F}^{\left(\alpha \right)}\left(\lambda \right)={\mathbb{E}}_{w,F}^{\left(\alpha \right)}(0;\lambda ),{\mathbb{G}}_{w,F}^{\left(\alpha \right)}\left(\lambda \right)={\mathbb{G}}_{w,F}^{\left(\alpha \right)}(0;\lambda ).$$

In light of the above studies, we define a new family of two-variable polynomials, including the polynomials defined by Equation (1) with the help of the Golden Calculus. Namely, we introduce the concept of the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials and numbers. Thus, we give some properties of this polynomial family, such as recurrence relations, sums formulae, and derivative relations, by using their generating function and functional equations. Additionally, we establish relationships between Apostol-type Frobenius–Euler–Fibonacci polynomials of order $\alpha$ and various other polynomial sequences, including Apostol-type Bernoulli–Fibonacci polynomials, Euler–Fibonacci polynomials, Genocchi–Fibonacci polynomials, and the Stirling–Fibonacci numbers of the second kind. We also introduce the new family of the generalized Apostol-type Frobenius–Euler–Fibonacci matrix and derive some factorizations of this newly established matrix. Finally, we provide zeroes and graphical illustrations for the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials.

2. Generalized Apostol-Type Frobenius–Euler–Fibonacci Polynomials ${\mathit{H}}_{\mathit{w},\mathit{F}}^{\left(\mathit{\alpha }\right)}(\mathit{\zeta },\mathit{\eta };\mathit{u};\mathit{\lambda })$

In this part, we introduce Apostol-type Frobenius–Euler–Fibonacci polynomials by means of the Golden Calculus. Some relations for these polynomials are also obtained by using various identities. At this point, we begin with the following definition.

Definition 1.

Let $\lambda \in \mathbb{C}$, $\alpha \in \mathbb{N}$, the generalized Apostol-type Frobenius–Euler polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α are defined by means of the following generating function:

$${\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}=\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}.$$

(20)

When $\zeta =\eta =0$ in (20), ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(u;\lambda )={\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,0;u;\lambda )$ are called the $w^{th}$ Apostol-type Frobenius–Euler–Fibonacci numbers of order $\alpha$.

Theorem 1.

The following summation formulas for the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α holds true:

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\sum _{s=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{s}}\right)}_F{\mathbb{H}}_{s,F}^{\left(\alpha \right)}(0,0;u;\lambda ){(\zeta +\eta )}_F^{w-s},$$

(21)

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\sum _{s=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{s}}\right)}_F{\mathbb{H}}_{s,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda ){\zeta }^{w-s}$$

(22)

and

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\sum _{s=0}^w{(-1)}^{\frac{s(s-1)}{2}}{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{s}}\right)}_F{\mathbb{H}}_{w-s,F}^{\left(\alpha \right)}(\zeta ,0;u;\lambda ){\eta }^s.$$

(23)

Proof. 

By virtue of (14)–(16) and (20), we obtain the desired results. □

Theorem 2.

The following recursive formulas for the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α hold true:

$$\frac{{\partial }_F}{{\partial }_F\zeta }\left\{{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\right\}=F_w{\mathbb{H}}_{w-1,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ),$$

(24)

$$\frac{{\partial }_F}{{\partial }_F\eta }\left\{{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\right\}=F_w{\mathbb{H}}_{w-1,F}^{\left(\alpha \right)}(\zeta ,-\eta ;u;\lambda ).$$

(25)

Proof. 

Differentiating both sides of (20) with respect to $\zeta$ and $\eta$ through Equation (13), we obtain (24) and (25), respectively. □

Theorem 3.

The following difference formulas for the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α holds true:

$$\lambda {\mathbb{H}}_{w,F}^{\left(\alpha \right)}(1,\eta ;u;\lambda )-u{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )=(1-u){\mathbb{H}}_{w,F}^{(\alpha -1)}(0,\eta ;u;\lambda )$$

(26)

and

$$\lambda {\mathbb{H}}_{w,F}^{\left(\alpha \right)}(1,0;u;\lambda )-u{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(1,-1;u;\lambda )=(1-u){\mathbb{H}}_{w,F}^{(\alpha -1)}(1,-1;u;\lambda ).$$

(27)

Proof. 

By virtue of (20), we can easily proof of Equations (26) and (27). We omit the proof. □

Theorem 4.

Let $\alpha ,\beta \in \mathbb{N}$, the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α hold true:

$${\mathbb{H}}_{w,F}^{(\alpha +\beta )}(\zeta ,\eta ;u;\lambda )=\sum _{s=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{s}}\right)}_F{\mathbb{H}}_{w-s,F}^{\left(\alpha \right)}(0,0;u;\lambda ){\mathbb{H}}_{s,F}^{\left(\beta \right)}(\zeta ,\eta ;u;\lambda ),$$

(28)

and

$${\mathbb{H}}_{w,F}^{(\alpha -\beta )}(\zeta ,\eta ;u;\lambda )=\sum _{s=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{s}}\right)}_F{\mathbb{H}}_{w-s,F}^{\left(\alpha \right)}(0,0;u;\lambda ){\mathbb{H}}_{s,F}^{(-\beta )}(\zeta ,\eta ;u;\lambda ).$$

(29)

Proof. 

Using generating function (20), we obtain Equations (28) and (29). We omit the proof. □

In the following theorems, we establish some results on the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order $\alpha$ and some relationships for Apostol-type Frobenius–Euler–Fibonacci polynomials of order $\alpha$ related to Apostol-type Bernoulli–Fibonacci polynomials, Apostol-type Euler–Fibonacci polynomials, and Apostol-type Genocchi–Fibonacci polynomials. We now begin with the following theorem.

Theorem 5.

For the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )$, one has

$$(2u-1)\sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{\mathbb{H}}_{l,F}(0,\eta ;u;\lambda ){\mathbb{H}}_{w-l,F}(\zeta ,0;1-u;\lambda )$$

$$=u{\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )-(1-u){\mathbb{H}}_{w,F}(\zeta ,\eta ;1-u;\lambda ).$$

(30)

Proof. 

We set

$$\frac{(2u-1)}{(\lambda e_F^d-u)(\lambda e_F^d-(1-u))}=\frac{1}{\lambda e_F^d-u}-\frac{1}{\lambda e_F^d-(1-u)}.$$

From the above equation, we see that

$$(2u-1)\frac{(1-u)e_F^{\zeta d}(1-(1-u))E_F^{\eta d}}{(\lambda e_F^d-u)(\lambda e_F^d-(1-u))}$$

$$=\frac{(1-u)e_F^{\zeta d}u{E}_F^{\eta d}}{\lambda e_F^d-u}-\frac{(1-u)e_F^{\zeta d}{E}_F^{\eta d}(1-(1-u))}{\lambda e_F^d-(1-u)},$$

through which, in using Equations (16) and (20) in both sides, we have

$$(2u-1)\left(\sum _{l=0}^{\infty }{\mathbb{H}}_{l,F}(0,\eta ;u;\lambda )\frac{d^l}{F_l!}\right)\left(\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(\zeta ,0;1-u;\lambda )\frac{d^w}{F_w!}\right)$$

$$=u\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}-(1-u)\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(\zeta ,\eta ;1-u;\lambda )\frac{d^w}{F_w!}.$$

By applying the Cauchy product rule in the aforementioned equation and subsequently comparing the coefficients of $d^w$ in both sides of the resulting equation, it can be deduced that assertion (30) holds true. □

Theorem 6.

For the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )$, one has

$$u{\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )=\lambda \sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{\mathbb{H}}_{l,F}(\zeta ,\eta ;u;\lambda )-(1-u){(\zeta +\eta )}_F^w.$$

(31)

Proof. 

Using the following identity

$$\frac{u}{\lambda (\lambda e_F^d-u)e_F^d}=\frac{1}{(\lambda e_F^d-u)}-\frac{1}{\lambda e_F^d},$$

we find that

$$\frac{u(1-u)e_F^{\zeta d}{E}_F^{\eta d}}{\lambda (\lambda e_F^d-u)e_F^d}=\frac{(1-u)e_F^{\zeta d}{E}_F^{\eta d}}{\lambda e_F^d-u}-\frac{(1-u)e_F^{\zeta d}{E}_F^{\eta d}}{\lambda e_F^d}$$

$$u\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}$$

$$=\lambda \sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }\frac{d^l}{F_l!}-(1-u)\sum _{w=0}^{\infty }{(\zeta +\eta )}_F^w\frac{d^w}{F_w!}.$$

By applying the Cauchy product rule in the aforementioned equation and subsequently comparing the coefficients of $d^w$ in both sides of the resulting equation, it can be deduced that assertion (31) holds true. □

Theorem 7.

For the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}(\zeta ,\eta ;u;\lambda )$ of order α, we obtain

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\frac{1}{1-u}\sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F\left[\lambda {\mathbb{H}}_{w-l,F}(1,\eta ;u;\lambda ){\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,0;u;\lambda )\right.$$

$$\left.-u{\mathbb{H}}_{w-l,F}(0,\eta ;u;\lambda ){\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,0;u;\lambda )\right].$$

(32)

Proof. 

Using (20), we find that

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}=\left(\frac{1-u}{\lambda e_F^d-u}\right)\left(\frac{\lambda e_F^d-u}{1-u}\right){\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}$$

$$=\frac{\lambda }{1-u}\left(\frac{1-u}{\lambda e_F^d-u}\right)e_F^d{\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}$$

$$-\frac{u}{1-u}\left(\frac{1-u}{\lambda e_F^d-u}\right){\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}.$$

Simplifying the above equation and using Equation (20), we obtain

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}=\frac{\lambda }{1-u}\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(1,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,0;u;\lambda )\frac{d^l}{F_l!}-$$

$$\frac{u}{1-u}\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,0;u;\lambda )\frac{d^l}{F_l!}.$$

By applying the Cauchy product rule in the aforementioned equation and subsequently comparing the coefficients of $d^w$ in both sides of the resulting equation, it can be deduced that assertion (32) holds true. □

Theorem 8.

The following relation between the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ and Apostol-type Bernoulli–Fibonacci polynomials ${\mathbb{B}}_{w,F}(\zeta ;\lambda )$ holds true:

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\sum _{l=0}^{w+1}{\left({\displaystyle \genfrac{}{}{0pt}{}{w+1}{l}}\right)}_F\left(\lambda \sum _{r=0}^l{\left({\displaystyle \genfrac{}{}{0pt}{}{l}{r}}\right)}_F{\mathbb{B}}_{l-r,F}(\zeta ;\lambda )-{\mathbb{B}}_{l,F}(\zeta ;\lambda )\right)$$

$$\times {\mathbb{H}}_{w-l+1,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda ).$$

(33)

Proof. 

Consider generating function (20), we have

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}$$

$$={\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}\left(\frac{d}{\lambda e_F^d-1}\right)\left(\frac{\lambda e_F^d-1}{d}\right)$$

$$=\frac{1}{d}\left(\lambda \sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{B}}_{l,F}(\zeta ;\lambda )\frac{d^l}{F_l!}\sum _{r=0}^{\infty }\frac{d^r}{F_r!}\right.$$

$$\left.-\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{B}}_{l,F}(\zeta ;\lambda )\frac{d^l}{F_l!}\right).$$

(34)

Using the Cauchy product rule in (34), the assertion (33) is obtained. □

Theorem 9.

The following relation between the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ and generalized Apostol-type Euler–Fibonacci polynomials ${\mathbb{E}}_{w,F}(\zeta ;\lambda )$ holds true:

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\frac{1}{2}\sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F\left(\lambda \sum _{r=0}^l{\left({\displaystyle \genfrac{}{}{0pt}{}{l}{r}}\right)}_F{\mathbb{E}}_{l-r,F}(\zeta ;\lambda )+{\mathbb{E}}_{l,F}(\zeta ;\lambda )\right){\mathbb{H}}_{w-l,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda ).$$

(35)

Proof. 

By virtue of (20), we have

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}$$

$$={\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}\left(\frac{2}{\lambda e_F^d+1}\right)\left(\frac{\lambda e_F^d+1}{2}\right)$$

$$=\frac{1}{2}\left(\lambda \sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{E}}_{l,F}(\zeta ;\lambda )\frac{d^l}{F_l!}\sum _{r=0}^{\infty }\frac{d^r}{F_r!}\right.$$

$$\left.+\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{E}}_{l,F}(\zeta ;u;\lambda )\frac{d^l}{F_l!}\right).$$

(36)

Using the Cauchy product rule in (36), the assertion (35) is obtained. □

Theorem 10.

The following relation between the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ and Apostol-type Genocchi–Fibonacci polynomials ${\mathbb{G}}_{w,F}(\zeta ;\lambda )$ holds true:

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\frac{1}{2}\sum _{l=0}^{w+1}{\left({\displaystyle \genfrac{}{}{0pt}{}{w+1}{l}}\right)}_F\left(\lambda \sum _{r=0}^l{\left({\displaystyle \genfrac{}{}{0pt}{}{l}{r}}\right)}_F{\mathbb{G}}_{l-r,F}(\zeta ;\lambda )+{\mathbb{G}}_{l,F}(\zeta ;\lambda )\right)$$

$$\times {\mathbb{H}}_{w-l+1,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda ).$$

(37)

Proof. 

Using (20), we obtain

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}$$

$$={\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}\left(\frac{2d}{\lambda e_F^d+1}\right)\left(\frac{\lambda e_F^d+1}{2d}\right)$$

$$=\frac{1}{2d}\left(\lambda \sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{G}}_{l,F}(\zeta ;\lambda )\frac{d^l}{F_l!}\sum _{r=0}^{\infty }\frac{d^r}{F_r!}\right.$$

$$\left.+\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(0,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{\mathbb{G}}_{l,F}(\zeta ;\lambda )\frac{d^l}{F_l!}\right).$$

(38)

Using the Cauchy product rule in (38), the assertion (37) is obtained. □

Theorem 11.

For the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α, we obtain

$${\mathbb{H}}_{w,F}^{(\alpha +1)}(\zeta ,\eta ;u;\lambda )=\sum _{s=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{s}}\right)}_F{\mathbb{H}}_{w-s,F}(u;\lambda ){\mathbb{H}}_{s,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ).$$

(39)

Proof. 

From (20), we obtain

$$\frac{1-u}{\lambda e_F^d-u}{\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}=\frac{1-u}{\lambda e_F^d-u}\sum _{s=0}^{\infty }{\mathbb{H}}_{s,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^s}{F_s!}$$

$$=\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}(u;\lambda )\frac{d^w}{F_w!}\sum _{s=0}^{\infty }{\mathbb{H}}_{s,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^s}{F_s!}.$$

Now, replacing w with $w-s$ and equating the coefficients of $d^w$ leads to Formula (39). □

Theorem 12.

For the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α, we have

$${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta +1,\eta ;u;\lambda )=\sum _{l=0}^w{\left(-1\right)}^{\left(\genfrac{}{}{0pt}{}{w-l}{2}\right)}{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ).$$

(40)

Proof. 

Using (20), we have

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta +1,\eta ;u;\lambda )\frac{d^w}{F_w!}-\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}$$

$$={\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}(E_F^d-1)$$

$$=\left(\sum _{l=0}^{\infty }{\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^l}{F_l!}\right)\left(\sum _{w=0}^{\infty }{\left(-1\right)}^{\left(\genfrac{}{}{0pt}{}{w}{2}\right)}\frac{d^w}{F_w!}\right)-\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}$$

$$=\sum _{w=0}^{\infty }\left(\sum _{l=0}^w{\left(-1\right)}^{\left(\genfrac{}{}{0pt}{}{w-l}{2}\right)}{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{\mathbb{H}}_{l,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\right)\frac{d^w}{F_w!}-\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}.$$

Finally, equating the coefficients of the like powers of $d^w$, we obtain (40). □

Theorem 13.

Let α and γ be non-negative integers. There is the following relationship between the numbers $S_F(w,l;\lambda )$ and the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ of order α, which holds true:

$$\alpha !\sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{\mathbb{H}}_{w-l,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )S_F\left(l,\alpha ;\frac{\lambda }{u}\right)={\left(\frac{1-u}{u}\right)}^{\alpha }{(\zeta +\eta )}_F^w$$

(41)

and

$${\mathbb{H}}_{w,F}^{(\alpha -\gamma )}(\zeta ,\eta ;u;\lambda )=\gamma !{\left(\frac{u}{1-u}\right)}^{\gamma }\sum _{l=0}^w{\left({\displaystyle \genfrac{}{}{0pt}{}{w}{l}}\right)}_F{\mathbb{H}}_{w-l,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )S_F\left(l,\gamma ;\frac{\lambda }{u}\right),$$

(42)

where $S_F(w,l;\lambda )$ is the Stirling–Fibonacci numbers of the second kind are defined by

$$\frac{{(\lambda e_F^d-1)}^l}{l!}=\sum _{w=0}^{\infty }{S}_F(w,l;\lambda )\frac{d^w}{F_w!}.$$

(43)

Proof. 

By virtue of (20), we find that

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}={\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}$$

$${\left(\lambda e_F^d-u\right)}^{\alpha }\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}={(1-u)}^{\alpha }\sum _{w=0}^{\infty }{(\zeta +\eta )}_F^w\frac{d^w}{F_w!}$$

$$\alpha !\frac{{\left(\frac{\lambda }{u}{e}_F^d-1\right)}^{\alpha }}{\alpha !}\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}={\left(\frac{1-u}{u}\right)}^{\alpha }\sum _{w=0}^{\infty }{(\zeta +\eta )}_F^w\frac{d^w}{F_w!}$$

$$\alpha !\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}\sum _{l=0}^{\infty }{S}_F\left(l,\alpha ;\frac{\lambda }{u}\right)\frac{d^l}{F_l!}$$

$$={\left(\frac{1-u}{u}\right)}^{\alpha }\sum _{w=0}^{\infty }{(\zeta +\eta )}_F^w\frac{d^w}{F_w!},$$

which, on rearranging the summation and then simplifying the resultant equation, yields the relation (41).

Once more, we examine the following arrangement of generating function (20) as:

$$\sum _{w=0}^{\infty }{\mathbb{H}}_{w,F}^{(\alpha -\gamma )}(\zeta ,\eta ;u;\lambda )\frac{d^w}{F_w!}={\left(\frac{1-u}{\lambda e_F^d-u}\right)}^{\alpha }{e}_F^{\zeta d}{E}_F^{\eta d}{\left(\frac{u}{1-u}\right)}^{\gamma }\gamma !\frac{{\left(\frac{\lambda }{u}{e}_F^d-1\right)}^{\gamma }}{\gamma !},$$

(44)

on use of Equations (44) and (20). After evaluation, the desired result is obtained (42). □

Now, we define the new family of generalized Apostol-type Frobenius–Euler–Fibonacci matrices. By using this definition, we obtain the factorizations of this newly established matrix in the following theorems.

Definition 2.

Let ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$ be the generalized Apostol-type Frobenius–Euler–Fibonacci polynomials. The $\left(n+1\right)\times \left(n+1\right)$ generalized Apostol-type Frobenius–Euler-Fibonacci matrix, ${\mathbf{H}}_{n,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )={\left[{\mathbf{h}}_{ij}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )\right]}_{i,j=0}^n$ is defined by

$${\mathbf{h}}_{ij}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=\left\{\begin{array}{cc}{\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F{\mathbb{H}}_{i-j,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )& i\ge j\\ 0& i<j\end{array}\right..$$

(45)

Theorem 14.

For the generalized Apostol-type Frobenius–Euler–Fibonacci matrix ${\mathbf{H}}_{n,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )$, we have

$${\mathbf{H}}_{n,F}^{(\alpha +\beta )}(\zeta +\psi ,\eta ;u;\lambda )={\mathbf{H}}_{n,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ){\mathbf{H}}_{n,F}^{\left(\beta \right)}(0,\psi ;u;\lambda ).$$

Proof. 

By virtue of (12), (16), (20), and (45), we find that

$$\begin{array}{ccc}\hfill {\mathbf{H}}_{n,F}^{(\alpha +\beta )}(\zeta +\psi ,\eta ;u;\lambda )& =& {\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F{\mathbb{H}}_{i-j,F}^{(\alpha +\beta )}(\zeta +\psi ,\eta ;u;\lambda )\hfill \\ & =& {\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F\sum _{k=0}^{i-j}{\left({\displaystyle \genfrac{}{}{0pt}{}{i-j}{k}}\right)}_F{\mathbb{H}}_{i-j-k,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ){\mathbb{H}}_{k,F}^{\left(\beta \right)}(0,\psi ;u;\lambda )\hfill \\ & =& \sum _{k=j}^i{\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F{\left({\displaystyle \genfrac{}{}{0pt}{}{i-j}{k-j}}\right)}_F{\mathbb{H}}_{i-k,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ){\mathbb{H}}_{k-j,F}^{\left(\beta \right)}(0,\psi ;u;\lambda )\hfill \\ & =& \sum _{k=j}^i{\left({\displaystyle \genfrac{}{}{0pt}{}{i}{k}}\right)}_F{\mathbb{H}}_{i-k,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ){\left({\displaystyle \genfrac{}{}{0pt}{}{k}{j}}\right)}_F{\mathbb{H}}_{k-j,F}^{\left(\beta \right)}(0,\psi ;u;\lambda )\hfill \\ & =& {\mathbf{H}}_{n,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda ){\mathbf{H}}_{n,F}^{\left(\beta \right)}(0,\psi ;u;\lambda ).\hfill \end{array}$$

□

Theorem 15.

For the generalized Apostol-type Frobenius–Euler–Fibonacci matrix ${\mathbf{H}}_{n,F}(\zeta ,\eta ;u;\lambda )$, we have

$${\mathbf{H}}_{n,F}(\zeta +\eta ,0;u;\lambda )={\mathbf{P}}_{n,F}\left(\zeta \right){\mathbf{H}}_{n,F}(0,\eta ;u;\lambda ),$$

where ${\mathbf{P}}_{n,F}\left(\zeta \right)={\left[{\mathbf{p}}_{ij}\left(\zeta \right)\right]}_{i,j=0}^n$ is the generalized Pascal matrix [23] via Fibonomial coefficients of the first kind is defined by

$${\mathbf{P}}_{n,F}\left(\zeta \right)=\left\{\begin{array}{cc}{\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F{\zeta }^{i-j}& i\ge j\\ 0& i<j\end{array}\right..$$

Proof. 

Using (45) and (12), we obtain

$$\begin{array}{ccc}\hfill {\mathbf{H}}_{n,F}(\zeta +\eta ,0;u;\lambda )& =& {\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F\sum _{k=0}^{i-j}{\left({\displaystyle \genfrac{}{}{0pt}{}{i-j}{k}}\right)}_F{\zeta }^{i-j-k}{\mathbb{H}}_{k,F}(0,\eta ;u;\lambda )\hfill \\ & =& \sum _{k=j}^i{\left({\displaystyle \genfrac{}{}{0pt}{}{i}{j}}\right)}_F{\zeta }^{i-k}{\left({\displaystyle \genfrac{}{}{0pt}{}{i-j}{k-j}}\right)}_F{\mathbb{H}}_{k-j,F}(0,\eta ;u;\lambda )\hfill \\ & =& \sum _{k=j}^i{\left({\displaystyle \genfrac{}{}{0pt}{}{i}{k}}\right)}_F{\zeta }^{i-k}{\left({\displaystyle \genfrac{}{}{0pt}{}{k}{j}}\right)}_F{\mathbb{H}}_{k-j,F}(0,\eta ;u;\lambda )\hfill \\ & =& {\mathbf{P}}_{n,F}\left(\zeta \right){\mathbf{H}}_{n,F}(0,\eta ;u;\lambda ).\hfill \end{array}$$

We investigate the beautiful zeros of the generalized Apostol-type Frobenius–Euler polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=0$ of order $\alpha$ by using a computer. We plot the zeros of generalized Apostol-type Frobenius–Euler polynomials ${\mathbb{H}}_{w,F}^{\left(\alpha \right)}(\zeta ,\eta ;u;\lambda )=0$ of order $\alpha$ for $w=30$ (Figure 1).

4. Conclusions

In this article, our objective was to introduce the F-analogues of the Apostol-type Frobenius–Euler polynomials, which we have denoted as generalized Apostol-type Frobenius–Euler–Fibonacci polynomials. We have employed the Golden Calculus to introduce these polynomials and subsequently explored their properties. Our work represents a generalization of the previously published articles [24]. In our future research studies, we intend to utilize the Golden Calculus to introduce the parametric types of certain special polynomials and to derive a plethora of combinatorial identities through their generating functions.
