约化C ~*-代数为单的线性群的刻划

Characterization of linear groups whose reduced C*-algebras are simple

Tal Poznansky

摘要:

证明了可数线性群G的约化C*-代数是单的当且仅当G不存在非平凡正规顺从子群.此外,这些条件被证明是等价于上述C*-代数上的迹态的唯一性。

英文摘要:

The reduced C*-algebra of a countable linear group G is shown to be simple if and only if G has no nontrivial normal amenable subgroups. Moreover, these conditions are shown to be equivalent to the uniqueness of tracial state on the aforementioned C*-algebra.
