Abstract
This paper deals with the existence of random mild solutions for some classes of first and second order functional evolution equations with random effects in Frechet spaces. The technique used is a generalization of the classical Darbo fixed point theorem for Frechet spaces associated with the concept of measure of noncompactness

Summary
There has been a significant development in functional evolution equations in recent years; see the monographs [2, 3, 17, 23, 25] and the references therein. In [1], an iterative method is used for the existence of mild solutions of evolution equations and inclusions. When our knowledge about the parameters of a dynamic system are of statistical nature, that is, the information is probabilistic, the common approach in mathematical modeling of such systems is the use of random differential equations or stochastic differential equations. We discuss the existence of random mild solutions for the evolution equation u (t, w) = A(t)u(t, w) + f (t, u(t, w), w); if t ∈ R+ := [0, ∞), w ∈ Ω,. We discuss the existence of random mild solutions for the following second order evolution problem. This paper initiates the existence of random mild solutions for evolution equations in Fréchet spaces with an application of a generalization of the classical Darbo fixed point theorem, and the concept of measure of noncompactness
