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 2 n -weakly amenable. Weak amenability of $$\ell ^1(S)$$ ℓ 1 ( S ) in terms of regular and irregular subsets of a commutative semigroup S is also studied.

关于半群代数弱顺应性的注记 

我们研究了某些可交换半群代数的弱适用性。首先,我们提出一类交换半群,其中半群代数(如任意群代数)总是 2 n -弱服从的。还研究了 $$\ell ^1(S)​​$$ ℓ 1 ( S ) 在交换半群 S 的正则和不规则子集方面的弱顺应性。
