Abstract:
  In this paper we study the existence of asymptotically almost periodic
  and almost periodic solutions for the partial evolution equation
  $$ \frac{d}{dt} (x(t)+g(t,x(t))=Ax(t)+f(t,Bx(t)),
  $$
  where $A$ is the infinitesimal generator of an analytic semigroup on a
  Banach space $X$, $B$ is a closed  linear operator, and $f$, $g$ are
  given functions.
