A note on essentially left -contractible Banach algebras
A. Sahami, I. Almasi
In this note, we show that \cite[Corollary 3.2]{sad} is not always true. In fact, we characterize essential left -contractibility of the the group algebras in the term of compac…
A note on left -biflat Banach algebras
A. Sahami, M. Rostami, A. Pourabbas
In this paper, we study the notion of -biflatness for some Banach algebras, where is a non-zero multiplicative linear functional. We show that the Segal algebra is le…
On left -biprojectivity and left -biflatness of certain Banach algebras
Amir Sahami
In this paper, we study left -biflatness and left -biprojectivity of some Banach algebras, where is a non-zero multiplicative linear function. We show that if the Banach…
Johnson pseudo-contractibility and pseudo-amenability of -Lau product of Banach algebras
M. Askari-Sayah, A. Pourabbas, A. Sahami
Given Banach algebras and with . We shall study the Johnson pseudo-contractibility and pseudo-amenability of -Lau product . We show that…
On the existence of an ultra central approximate identity for certain semigroup algebras
A. Sahami, I. Almasi
In this paper we characterize the existance of an ultra central approximate identity for , where is a uniformly locally finite inverse semigroup. As an application…
