Relative Controllability of ψ-Caputo Fractional Neutral Delay Differential System

The aim of this work is to analyze the relative controllability and Ulamn–Hyers stability ψ-Caputo fractional neutral delay differential system. We use ψ-delayed perturbation Mitttag–Leffler matrix function Banach contraction principle examine Ulam–Hyers our considered formulate Grammian establish results linear fractonal Further, we employ fixed-point technique Krasnoselskii’s type sufficient conditions for a semilinear Finally, theoretical study validated by providing an application.
