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…
Strong pseudo-Connes amenability of dual Banach algebras
S. F. Shariati, A. Pourabbas, A. Sahami
In this paper, we introduce the new notion of strong pseudo-Connes amenability for dual Banach algebras. We study the relation between this new notion to the various notions of Con…
On approximate Connes-biprojectivity of dual Banach algebras
S. F. Shariati, A. Pourabbas, A. Sahami
In this paper, we introduce a notion of approximate Connes-biprojectivity for dual Banach algebras. We study the relation between approximate Connes-biprojectivity, Johnson pseudo-…
Strong pseudo-amenability of some Banach algebras
Amir Sahami
In this paper we introduce a new notion of strong pseudo-amenability for Banach algebras. We study strong pseudo-amenability of some Matrix algebras. Using this tool, we characteri…
