Time-fractional telegraph equation with ψ-Hilfer derivatives

Chaos, Solitons & Fractals, 2022
This paper deals with the investigation of the solution of the time-fractional telegraph equation in higher dimensions with $\psi$-Hilfer fractional derivatives. By application of the Fourier and $\psi$-Laplace transforms the solution is derived in closed form in terms of bivariate Mittag-Leffler functions in the Fourier domain and in terms of ...

Fractional optimal reachability problems withψ‐Hilfer fractional derivative

Mathematical Methods in the Applied Sciences, 2022
The aim of this article is to investigate the optimal reachability problem in terms of theψ‐Hilfer fractional derivative for a fractional dynamical system. Euler–Lagrange equations are used to obtain the necessary optimality constraints for the fractional optimal reachability problem (FORP).

An operational calculus approach to Hilfer–Prabhakar fractional derivatives

Banach Journal of Mathematical Analysis, 2023
The authors employ Mikusiński's operational calculus to study the Hilfer-Prabhakar fractional derivative operator. By using an algebraic interpretation of the latter derivative, a number of fractional differential equations are solved.
