  • Abstract
    The main purpose of this paper is to investigate weak amenability of semigroup algebras. We relate this to a new notion of weak amenability modulo an ideal of Banach algebras. As an important result, we show that l1(S) is weakly amenable modulo Iσ , where Iσ is the corresponding ideal of the group congruence σ.
