Approximate (σ-τ)-Contractibility
Abstract
In this paper, the generalized Hyers--Ulam--Rassias stability of (σ-τ)-derivations on normed algebras into Banach bimodules is established. We introduce the notion of approximate (σ-τ)-contractibility and prove that a Banach algebra is (σ-τ)-contractible if and only if it is approximately (σ-τ)-Contractible.
