Existence and ulam stability of k-generalized ψ-Hilfer fractional problem

Abstract

<jats:p>In this paper, we prove existence, uniqueness stability results for a class of initial value problem for fractional differential equations involving generalized ψ-Hilfer fractional derivative. The result is based on the Banach contraction mapping principle. In addition, two examples are given to illustrate our results.</jats:p>
