摘要

In this paper, we give suffcient conditions to get the existence of mild so- lutions for two classes of first order partial and neutral of perturbed evolution equations by using the nonlinear alternative of Avramescu for contractions op- erators in Frechet spaces, combined with semigroup theory. The solution here is depending on an infinite delay and is giving on the real half-line.
