摘要
In this paper we prove the existence of weighted pseudo almost periodic mild solutions for the class of integro-differential equations in the form u'(t) = Au(t) + alpha integral(t)(-infinity) e(-beta(t-s)) Au(s) ds + f(t, u(t)) where f (., u(.)) is a Stepanov-like weighted pseudo almost periodic function and A generates an immediately norm continuous C-0-semigroup on a Banach space X. Also, we give a short proof to show that the vector-valued space of Stepanov-like weighted pseudo almost periodic functions is a Banach space.
