In this paper, we study the notion of approximate biprojectivity and left φ-biprojectivity of some Banach algebras, where φ is a character. Indeed, we show that approximate biprojectivity of the hypergroup algebra L1K implies that K is compact. Mor

In this paper, we investigate the existence of an ultra central approximate identity for a Banach algebra A and its second dual A∗∗. Also, we prove that for a left cancellative regular semigroup S, ℓ1S∗∗ has an ultra central approximate ide

In this paper, the concept of left ϕ-approximate Connes amenability for a dual Banach algebra 𝒜 {\mathcal{A}} is studied, where ϕ is a weak * {{}^{*}} -continuous multiplicative linear functional on 𝒜 {\mathcal{A}} . Some characterizations fo

In this paper, we study some amenability like properties for certain matrix algebras called anti-symmetric matrix algebras, say $AS_I(\Bbb C)$, where the index set $I$ is a totally ordered set which posses a smallest element. We show that anti-symmet

In this paper, we introduce and study the notion of left [Formula: see text]-essential Connes amenable for dual Banach algebras. We investigate the hereditary properties of this new concept and we give some results for [Formula: see text]-Lau product
