Abstract

In this paper we define a new type of the fractional derivative, which we call tempered Ψ−Caputo fractional derivative. It is a generalization of the tempered Caputo fractional derivative and of the Ψ−Caputo fractional derivative. The Cauchy problem for fractional differential equations with this type of derivative is discussed and some existence and uniqueness results are proved. We present a Henry-Gronwall type inequality for an integral inequality with the tempered Ψ−fractional integral. This inequality is applied in the proof of an existence theorem. A result on a representation of solutions of linear systems of Ψ−Caputo fractional differential equations is proved and in the last section an example is presented.

Highlights

  • Inspired by the papers [10,39,41], we define a modification of the Ψ −Caputo derivative, which we call the tempered Ψ −Caputo derivative and we study the Cauchy problem for fractional differential equations with this type of fractional derivative

  • The main aim of this paper is to present some results on the existence and uniqueness of solutions of fractional differential equations with the tempered Ψ −Caputo derivative

  • We proposed a new type of fractional derivative, which we call the tempered Ψ −Caputo fractional derivative

Summary

Introduction

Brestovanska have been defined in recent decades They are more general and more suitable for applications than the Riemann-Liouville fractional derivative. In the recently published papers [12, 23, 37] so-called tempered Riemann-Liouville and tempered Caputo fractional derivatives are defined. Inspired by the papers [10,39,41], we define a modification of the Ψ −Caputo derivative, which we call the tempered Ψ −Caputo derivative and we study the Cauchy problem for fractional differential equations with this type of fractional derivative This derivative includes as special cases the tempered Caputo [23]. The main aim of this paper is to present some results on the existence and uniqueness of solutions of fractional differential equations with the tempered Ψ −Caputo derivative
