Existence and Uniqueness Analysis for Fractional Differential Equations with Nonlocal Conditions

Abstract

Fractional differential equations and systems are gradually becoming an essential approach to real world applications in science and engineering technology. The boundary value problems of the fractional differential equations and systems were investigated by using several different methods. Recently, much attention has been paid to investigate fractional differential equations with nonlocal conditions by using the fixed point method. In this paper, by using the Banach fixed point theorem and Krasnoselkii fixed point theorem, the existence and uniqueness of the solutions to the initial value problem of the nonlinear fractional differential equations with nonlocal conditions are investigated, and some sufficient conditions are obtained. We extend some results that already exist. Finally, an example is given to show the usefulness of the theoretical results.
