Abstract

We continue \cite{sp1 glas} and we discuss approximately left $\varphi$-biprojectivity for $\theta$-Lau product algebras. We give some Banach algebras among the category of $\theta$-Lau product algebras which are not approximately left $\varphi$-biprojective. In fact, some class of matrix algebras under the notion of approximate left $\varphi$-biprojectivity is also discussed here.
