In this paper, we prove the existence of a continuous one-to-one correspondence between bounded solutions of the equation x′(t) = Ax(t) + b(t) which belong to a certain subclass L+ of and bounded mild solutions of the equation x′(t) = Ax(t) + b(t) + f(t, x(t)) of the form u(t) = ø(t) + Ψ(t), with ø(t) ∈ L+ and .
