چکیده
|
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 l ^1 (s) is weakly amenable modulo iσ, where iσ is the corresponding ideal of the group congruence σ.
