Existence and uniqueness of classical and mild solutions of fractional Cauchy problem with impulses

Abstract

In this manuscript, we have established conditions for the existence and uniqueness of mild and classical solutions to the fractional order Cauchy problem by including and without including impulses over the completed norm linear space (Banach space). Conditions are established using the concept of generators and the generalised Banach fixed point theorem, which are weaker conditions than the previously derived conditions. We have also established the conditions under which a mild solution to the problem gives rise to a classical solution to the given problem. Finally, illustrations of the existence and uniqueness of the solution are provided to validate our derived results.
