Qualitative Analysis of Generalized Proportional Fractional Functional Integro-Differential Langevin Equation with Variable Coefficient and Nonlocal Integral Conditions

abstract:
In this paper, the existence and uniqueness of solutions for a nonlinear generalized proportional fractional functional integro-differential Langevin equation involving variable coefficient via nonlocal multi-point integral conditions are investigated by using Banach's, Schaefer's and Krasnoselskii's fixed point theorems. Different types of Ulam-Hyers stability are also established. Finally, an example is given to demonstrate applicability to the theoretical findings.
