Abstract
This research paper intends to investigate some qualitative analysis for a nonlinear Langevin integro-fractional differential equation. We investigate the sufficient conditions for the existence and uniqueness of solutions for the proposed problem using Banach's and Krasnoselskii's fixed point theorems. Furthermore, we discuss different types of stability results in the frame of Ulam-Hyers by using a mathematical analysis approach. The obtained results are illustrated by presenting a numerical example.
