Stepanov-like almost automorphic solutions for nonautonomous evolution equations

Samir Fatajou, Nguyen Van Minh, Gaston M. N'Guerekata, Alexander Pankov

Abstract:
We study the convolution of Stepanov-like almost automorphic functions and L^1 functions. Also we consider nonautonomous evolution equations, with a periodic operator coefficient and Stepanov-like almost automorphic forcing, and show that, under certain assumptions, any bounded mild solution is almost automorphic.
