Cyclic amenability of Lau product and module extension Banach algebras

پژوهش‌های ریاضی, 2022
Introduction The notion of weak amenability for commutative Banach algebras was introduced and studied for the first time by Bade, Curtis and Dales. Johnson extended this concept to the non commutative case and showed that group algebras of all locally ...

Derivations on triangular Banach algebras of order three

, 2013
In this paper, we define some new notions of triangular Banach algebras and we investigate the derivations on these algebras.

The Perturbation of the Sub-Noncommutative Pseudo-Browder Essential Spectrum of Bounded Upper Triangular Operator Matrices

Axioms
Let ε>0 and TB(X×X) be the Banach algebra of all 2×2 bounded upper triangular operator matrices on a separable Hilbert space X×X. In this paper, we first establish the spectrum equalities for special cases of upper triangular operator matrices—diagonal ...

Module derivations into iterated duals of triangular Banach algebras

Filomat
Let A be a Banach algebra, A and B be Banach A-module with compatible actions and X be a Banach left A-A-module and Banach right B-A-module. Then the corresponding triangular Banach algebra Tri(A,X, B) is a Banach A-module with compatible actions.

Vanishing of the first $(σ,τ)$-cohomology group of triangular Banach algebras

, 2005
In this paper, we define the first topological $(σ,τ)$-cohomology group and examine vanishing of the first $(σ,τ)$-cohomology groups of certain triangular Banach algebras. We apply our results to study the $(σ,τ)$-weak amenability and $(σ,τ)$-amenability of triangular Banach algebras.

Connes Biprojectivity in Dealing With Nilpotent Ideals and Triangular Dual Banach Algebras

Journal of Mathematics
In this paper, we investigate specific properties of nilpotent ideals within approximately Connes biprojective dual Banach algebras. Consequently, it establishes necessary and sufficient conditions for the Connes biprojectivity of triangular dual Banach algebras.
