Abstract

In this paper we prove the existence of mild solutions for semilinear differential equations in a Banach space. The results are obtained by using the semigroup theory and the Schaefer fixed point theorem. An example is provided to illustrate the theory.

Keywords: semilinear differential equation, mild solution, Schaefer fixed point theorem
