A Note on phi-Approximate Biflatness of a Semogroup Algebra
Behrooz Olfatian Gillan *, Amir Sahami
Abstract:   (841 Views)

‎In this note‎, ‎we show that cite[Theorem 2.3]{ghorb} is not true‎. ‎In fact‎, ‎we show that $ell^{1}(mathbb{N}_{max})$ is a unital Banach algebra which is $phi$-pseudo amenable but it is not $phi$-approximate biflat for some $phiin Hom(ell^{1}(mathbb{N}_{max}))$‎.

Keywords: Semigroup algebras‎, ‎$phi$-approximate biflatness‎, ‎amenability
