摘要：
We study weak amenability of certain classes of commutative semigroup algebras. First, we present a class of commutative semigroups which semigroup algebras (like arbitrary group algebras) are always 2n-weakly amenable. Weak amenability of l(1)(S) in terms of regular and irregular subsets of a commutative semigroup S is also studied.
