Special Issue Information

In recent years, fractional calculus has allowed us to describe several complex problems in the fields of mathematics, physics, biology, economics, and engineering. The complexity of these problems has led researchers to develop mathematical theories to model the complexities of nature by taking into account fractional calculus. Mathematical models are powerful tools that can be used to describe real-world problems; to develop mathematical models, differential equations and differential operators are required. At present, the literature contains two classes of differential operators, namely local and non-local operators (divided into three kinds: differential operators with a power-law kernel, differential operators with exponential decay, differential operators with the Mittag-Leffler function, and finally fractal-fractional operators). 

This Special Issue will focus on the theory and applications of fractional-order derivatives and fractional-order integrals in different aspects of Chaos and Statistics. We welcome manuscripts regarding complex dynamical systems, nonlinearity, chaos, synchronization, neural networks, or fractional dynamics in computational biology. 

The Special Issue will explore fundamental and application issues with the new derivatives in established areas of scientific computation, chaos and statistics, and emerging fields. 

Potential topics include, but are not limited to, the application of fractional differential operators to:

  • fractional calculus;
  • chaotic processes;
  • computational biology;
  • non-Markovian processes;
  • power-law kernels;
  • exponential kernels;
  • Mittag-Leffler derivatives;
  • fractal-fractional derivatives;
  • fractional control;
  • fractional estimation;
  • signal processing;
  • artificial neural networks; and
  • image processing.

A novel approach to solve optimal control problems dealing simultaneously with fractional differential equations and time delay is proposed in this work. More precisely, a set of global radial basis functions are firstly used to approximate the states and control variables in the problem. Then, a collocation method is applied to convert the time-delay fractional optimal control problem to a nonlinear programming one. By solving the resulting challenge, the unknown coefficients of the original one will be finally obtained. In this way, the proposed strategy introduces a very tunable framework for direct trajectory optimization, according to the discretization procedure and the range of arbitrary nodes. The algorithm’s performance has been analyzed for several non-trivial examples, and the obtained results have shown that this scheme is more accurate, robust, and efficient than most previous methods.

Chaotic dynamical systems are studied in this paper. In the models, integer order time derivatives are replaced with the Caputo fractional order counterparts. A Chebyshev spectral method is presented for the numerical approximation. In each of the systems considered, linear stability analysis is established. A range of chaotic behaviours are obtained at the instances of fractional power which show the evolution of the species in time and space. Full article
