| Abstract: | We study the existence of almost automorphic solutions of differential equations with infinite delay in abstract space.We prove that the existence of a bounded solution on R+ implies the existence of an almost automorhic solution and give an application to Lotka-Volterra type equation.Our result extends the classical result on the existence of almost periodic solutions for inhomegeneous linear almost periodic differential equations. |
