Journal of Mathematical Extension, 2015 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).

Banach Algebras of Quasi-Triangular Operators Are Spectrally Regular
Linear Algebra and Its Applications, 2013 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
Journal of Mathematical Extension, 2014 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 ...

Structure of Certain Banach Algebra Products [PDF]
Journal of Sciences, Islamic Republic of Iran, 2014 Let and be Banach algebras, , and . We define an -product on which is a strongly splitting extension of by . We show that these products form a large class of Banach algebras which contains all module extensions and triangular Banach algebras.

Generalized π-Baer *-rings [PDF]
Journal of Algebraic Systems, 2023 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 $Y$

Classification of limits of upper triangular matrix algebras. [PDF]
, 1993 Let Tn be the operator algebra of upper triangular n × n complex matrices. Three families of limit algebras of the form lim (Tnk) are classified up to isometric algebra isomorphism: (i) the limit algebras arising when the embeddings Tnk→Tnk+1, are ...

Conditions implying the uniqueness of the weak*-topology on certain group algebras [PDF]
, 2009 We investigate possible preduals of the measure algebra M(G) of a locally compact group and the Fourier algebra A(G) of a separable compact group. Both of these algebras are canonically dual spaces and the canonical preduals make the multiplication ...
