$\sigma$-Approximately Contractible Banach Algebras

Abstract

We investigate $\sigma$-approximate contractibility and $\sigma$-approximate amenability of Banach algebras, which are extensions of usual notions of contractibility and amenability, respectively, where $\sigma$ is a dense range or an idempotent bounded endomorphism of the corresponding Banach algebra.
