Let S be an inverse semigroup with the set of idempotents E. We prove
that the semigroup algebra β1(S) is always 2n-weakly module amenable
as an β1(E)-module, for any nβN, where E acts on S
trivially from the left and by multiplication from the right.Comment: arXiv admin note: text overlap with arXiv:1207.4514 by other author
