Approximate biprojectivity of certain semigroup algebras
A. Sahami, A. Pourabbas
In this paper, we investigate the notion of approximate biprojectivity for semigroup algebras and for some Banach algebras related to semigroup algebras. We show that …

Approximate biprojectivity and -biflatness of certain Banach algebras
A. Sahami, A. Pourabbas
In this paper we are going to investigate the approximate biprojectivity and the -biflatness of some Banach algebras related to the locally compact groups. We show that a Segal…

On homological notions of Banach algebras related to a character
A. Sahami
In this paper, we countinue our work in \cite{11}. We show that is -biprojective if and only if is compact, where is the augmentation character. We…
