چکیده
|
This paper continues the investigation initially begun in [24]. weshow 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.
