MF-property for countable discrete groups

Abstract

In this article we study MF-property for countable discrete groups, i.e. groups which admit embedding into unitary group of $C^{\ast }$-algebra $\prod M_n/\oplus M_n$. We prove that Baumslag group $⟨a,b|a^{a^b}=a^2⟩$ has MF-property and check some permanent facts about MF-groups.
