Abstract

In this paper, we introduce the concept of approximate Connes I-biprojectivity for Banach algebras, where I is a w∗-closed ideal on A. We explore several hereditary properties associated with this notion and provide illustrative examples that distinguish it from classical concepts. Finally, we offer a characterization of approximate Connes biprojectivity for upper triangular matrix Banach algebras and certain semigroup algebras.
