Johnson pseudo-Connes amenability of dual Banach algebras

Abstract

We introduce the notion of Johnson pseudo-Connes amenability for dual Banach algebras. We study the relation between this new notion with the various notions of Connes amenability like Connes amenability, approximate Connes amenability and pseudo Connes amenability. We also investigate some hereditary properties of this new notion. We prove that for a locally compact group GG, M(G)M(G) is Johnson pseudo-Connes amenable if and only if GG is amenable. Also we show that for every non-empty set II, MI(C)\mathbb{M}_I(\mathbb{C}) under this new notion is forced to have a finite index. Finally, we provide some examples of certain dual Banach algebras and we study their Johnson pseudo-Connes amenability.
