We prove that L1(G, A) is approximatelyweakly amenable where A is a unital separable Banach algebra. We givenecessary and sufficient conditions for the existence of a left invariant meanon L∞(G, A∗), LUC(G, A∗), WAP(G, A∗) and C0(G, A∗). %U https://jas.shahroodut.ac.ir/article_610_80140794b33ad022f3303e700e885240.pdf
