Module super-amenability for semigroup algebras

Functional Analysis 2009-12-24 v1

Abstract

Let SS be an inverse semigroup with the set of idempotents EE. In this paper we define the module super-amenability of a Banach algebra which is a Banach module over another Banach algebra with compatible actions, and show that when EE is upward directed and acts on SS trivially from left and by multiplication from right, the semigroup algebra 1(S) \ell ^{1}(S) is 1(E)\ell^{1}(E)-module super-amenable if and only if an appropriate group homomorphic image of SS is finite.
