Existence and Stability Analysis for Caputo Generalized Hybrid Langevin Differential Systems Involving Three-Point Boundary Conditions

Abstract

This research inscription gets to grips with two novel varieties of boundary value problems. One of them is a hybrid Langevin fractional differential equation, whilst the other is a coupled system of hybrid Langevin differential equation encapsuling a collective fractional derivative known as the psi-Caputo fractional operator. Such operators are generated by iterating a local integral of a function with respect to another increasing positive function psi. The existence of the solutions of the aforehand equations is tackled by using the Dhage fixed point theorem, whereas their uniqueness is handled using the Banach fixed point theorem. On the top of this, the stability within the scope of Ulam-Hyers of solutions to these systems are also considered. Two pertinent examples are presented to corroborate the reported results.
