| چکیده | ||
| This paper continues the investigation initially begun in [24]. We show that left ϕ-biflatness and left ϕ-biprojectivity are closely related to the notions of left ϕ-amenability and ϕ-inner amenability. We characterize left ϕ-biprojectivity and left ϕ-biflatness of certain semigroup algebras and some algebras related to a locally compact group. We discuss non left ϕ-biflatness of some specified triangular Banach algebras. | ||
