Abstract
In this paper, we study existence and uniqueness of solutions for nonlocal boundary value problems of Caputo fractional differential equations equipped with generalized Riemann-Liouville integral boundary conditions. A variety of fixed point theorems such as Banach's fixed point theorem, nonlinear contractions, Krasnoselskii's fixed point theorem, Schaefer's fixed point theorem, Leray-Schauder's nonlinear alternative and Leray-Schauder degree theory are applied to obtain the desired results. Several examples are discussed for illustration of the obtained results.
