Abstract

In a Banach space, if u is a Stepanov almost periodic solution of a certain nth-order infinitesimal generator and time-dependent operator differential equation with a Stepanov almost periodic forcing function, then u,u,,u(n2) are all strongly almost periodic and u(n1) is weakly almost periodic.
