Cadi Ayyad, Morocco) Said Boulite (Univ. Cadi Ayyad, Morocco) Gaston M. N'Guerekata (Morgan State Univ., Baltimore, MD, USA) Lahcen Maniar (Univ. Cadi Ayyad, Morocco) Abstract: This paper studies the existence and uniqueness of almost automorphic mild solutions to the semilinear parabolic evolution equation $$ u'(t)=A(t)u(t)+f(t, u(t)), $$ assuming that the linear operators $A(\cdot)$ satisfy the Acquistapace-Terreni conditions, the evolution family generated by $A(\cdot)$ has an exponential dichotomy, and the resolvent $R(\omega,A(\cdot))$, and $f$ are almost automorphic.
