Abstract

In this paper, we study (\mu,\nu)-pseudo almost automorphic solutions for the nonlinear differential equation x'(t)=A(t)x(t)+f(t,x(t)) for t\in \mathbb{R}, where A(t) is n\times n matrix and f:\mathbb{R}\times\mathbb{R}^{n}\rightarrow\mathbb{R}^{n} is an (\mu,\nu)-pseudo almost automorphic function satisfying the following condition |f(t,x)-f(t,y)|\leq l(t)h(|x-y|), where l\in L^{p}(\mathbb{R})\cap L^{\infty}(\mathbb{R})\;(1<p<+\infty) and h:[0,+\infty)\rightarrow [0,+\infty) is a nondecreasing function continuous on [0,+\infty[, verifying  h(r)<r for every r>0 and h(0)=0. The main tools are exponential dichotomy and a fixed point theorem. This work is motivated by the work [1] where there are a number of inaccuracies in the proof of the main result. An example is given to illustrate the theory.
