The existence, uniqueness and Ulam-Hyers stability results of a hybrid coupled system with Ψ-Caputo fractional derivatives

In this paper, the existence of unique solution is established for a coupled system of fractional differential equations that involves psi-Caputo fractional derivatives using the Banach contraction principle. we also discover at least one solution to the aforementioned system by employing certain assumptions and the Leray-Schauder alternative fixed point theorem. Subsequently, the Ulam-Hyers stability is discussed. Finally, a relevant example is utilized to support the main findings.
