A new class of ideal Connes amenability

Abstract

In this paper, we introduce a new notion of amenability, $\sigma-$Connes ideal, say, for a large class of dual Banach algebras. We extend the concept of ideal Connes amenability and study their properties. Let $\sigma$ be a $weak^{*}$-continuous endomorphism on a dual Banach algebra $\mathcal{A}$ with dense range. Then the concept of ideal Connes-amenability and $\sigma-$ ideally Connes amenability are the same. We gave some general results and hereditary properties with some examples for this new notion of amenability.
