Abstract

In this paper, we study the existence of mild solutions for fractional semilinear integro-differential equations in an arbitrary Banach space associated with operators generating compact semigroup on the Banach space. The arguments are based on the Schauder fixed point theorem.

Summary

Introduction

The purpose of the present paper is to present an alternative approach to the existence of solution of fractional semilinear integro-differential equations in an arbitrary Banach space X of the form x t A t x t f. In order to prove the existence of fixed points, we shall rely on the Schauder theorem. An application to fractional differential equations is provided to illustrate the results of this work
