Special Issue Information
Dear Colleagues,
In recent decades, fractional calculus increased its popularity due to the awareness that many physical problems, such as viscoelasticity, Brownian motions, and so on, need fractional derivatives to be modeled. For some problems, there are analytical solutions. These are expressed through the Mittag Leffer function, which is a series expansion and thus needs to be computed with numerical tools. For this reason and for the other unsolved problems, the literature has identified many ways to numerically solve fractional differential problems. Many methods use finite difference for the integer derivative and the quadrature rule for the fractional one. Others use spectral or Galerkin methods. In recent years, the collocation method has also proved to be easy and efficient to implement. Many papers have proved that spectral, Galerkin or collocation methods can be particularly efficient and accurate when special functions are used. Using, for example, the B-spline functions, one can get a multiresolution analysis, i.e., a sequence of nested approximating spaces that cover L²(R). It should be emphasized that the fractional derivative of a B-spline is a fractional B-spline. In this Special Issue, of particular interest are the following subtopics:
- Fractional ordinary differential equations (FODE)
- Fractional partial derivative equations (FPDE)
- Collocation methods
- Galerkin methods
- Spectral methods
- Convergence analysis
- Fractional B-splines

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fractal and Fractional is an international peer-reviewed open access monthly journal published by MDPI.
