Abstract

We will study some permanence properties of C&ast;-unique groups in details. In particular, normal subgroups and extensions will be considered. Among other interesting results, we prove that every second countable amenable group with an injective finite-dimensional representation (not necessarily unitary) is a retract of a C&ast;-unique group. Moreover, any amenable discrete group is a retract of a discrete C&ast;-unique group. [Copyright &y& Elsevier]
