On \(*\)-wild algebras (Q2711735)

Denote by \(C^*(F)\) the group \(C^*\)-algebra of a discrete group \(F\). \( F\) is called \(*\)-wild if for some \(n\) there exists an epimorphism \(C^*(F) \to M_n(C^*(F_2)),\) where \(F_2\) is a free group with two generators. The author proposes two methods of constructing new examples of \(*\)-wild discrete groups, different from semi-direct products \(F\otimes G,\) where \(F\) is a \(*\)-wild group.NEWLINENEWLINEFor the entire collection see [Zbl 0937.00046].
