EXISTENCE AND UNIQUENESS RESULTS FOR A COUPLED SYSTEM OF NONLINEAR FRACTIONAL LANGEVIN EQUATIONS

Abstract

In this paper, we present a sufficient condition for the unique existence of solutions for a coupled system of nonlinear fractional Langevin equations with a new class of multipoint and nonlocal integral boundary conditions. We define a 𝓩*λ-contraction mapping and present the sufficient condition by identifying the problem with an equivalent fixed point problem in the context of b-metric spaces. Finally, some numerical examples are given to validate our main results.
