Various notions of module amenability on weighted semigroup algebras

Abstract

Let SS be an inverse semigroup with the set of idempotents EE. In this article, we find necessary and sufficient conditions for the weighted semigroup algebra l1(S,ω){l}^{1}\left(S,\omega ) to be module approximately amenable (contractible) and module character amenable (as l1(E){l}^{1}\left(E)-module).
