Abstract :
In this paper, we shall deal with $mu$-pseudo almost automorphic solutions to the nonautonomous semilinear evolution equations: $u’(t)=A(t)u(t)+f(t,u(t-h))$, $tin mathbb{R}$ in a Banach space $mathbb{X}$, where $A(t)$, $tin mathbb{R}$ generates an exponentially stable evolution family ${U(t,s)}$ and $f:mathbb{R} imesmathbb{X} ightarrowmathbb{X}$ is a $mu$-pseudo almost automorphic function satisfying some suitable conditions. We obtain our main results by properties of $mu$-pseudo almost automorphic functions combined with theories of exponentially stable evolution family.
Keywords :
$mu$-pseudo almost automorphic function, nonautonomous semilinear evolution equations, fixed point.
