Abstract

In this article we solve the Cauchy problem for the relaxation equation posed in a framework of variable order fractional calculus. After introducing some general mathematical theory we establish concepts of Scarpi derivative and transition functions which represent the essentials of our problem. Next, we provide an expression in terms of an integral for the solution of our initial value problem where the transition function is chosen arbitrary. Finally, we provide the special case of the integral for the solution in the case of an exponential-type transition function, as well as in the case of a Mittag-Leffler transition.
