摘要：

Let A be a Banach algebra and let I be a closed two-sided ideal in A. A is I-weakly amenable if H-1(A, I*) = {0}. Further, A is ideally amenable if A is I-weakly amenable for every closed two-sided ideal I in A. In this paper we introduce s-ideal amenability for a Banach algebra A, where sigma is an idempotent bounded endomorphism of A.
