Banach Algebras of Quasi-Triangular Operators Are Spectrally Regular
The concept of spectrally regular algebra is introduced in this paper. The subalgebra of bounded operators containing all quasidiagonal operators is considered. It is proven that this subalgebra is spectrally regular. This result is an analogue of the scalar case, concerning analytic functions not having zeros in a given field.

On Weak Generalized Amenability of Triangular Banach Algebras
Let A1, A2 be unital Banach algebras and X be an A1 − A2− module. Applying the concept of module maps, (inner) module generalized derivations and generalized first cohomology groups, we present several results concerning the relations between module ...

Let A and B be unital Banach algebras and M be a left A-module and right B-module. We consider generalized derivations associate with Hochschild 2-cocycles on triangular Banach algebra T (related to A, B and M).

Generalized π-Baer *-rings [PDF]
A *-ring $R$ is called a generalized $\pi$-Baer *-ring, if for any projection invariant left ideal $Y$ of $R$, the right annihilator of $Y^n$ is generated, as a right ideal, by a projection, for some positive integer $n$, depending on $Y$

Approximate Biprojectivity of ℓ1-Munn Banach Algebras
In the present paper, we study the approximate biprojectivity and weak approximate biprojectivity of ℓ1-Munn Banach algebras when the related sandwich matrix is regular over InvA.

On Amenability-Like Properties of a Class of Matrix Algebras
In this study, we show that a matrix algebra ℒℳIpA is a dual Banach algebra, where A is a dual Banach algebra and 1≤p≤2. We show that ℒℳIpℂ is Connes amenable if and only if I is finite, for every nonempty set I.

Factorisation of orthogonal projectors
We study the problem of a special factorisation of an orthogonal projector~$P$ acting in the Hilbert space $L_2(\mathbb R)$ with $\dim\ker ...
