Extensions of Groups and Simple C*-Algebras

Part of the Operator Theory: Advances and Applications book series (OT, volume 43)


Since Powers ([9]) proved that the reduced C*-algebra of the free group on two generators C r * (F2) is simple with unique trace, several other classes consisting of discrete groups G such that C r * (G) is simple with unique trace have been produced (see e.g. [1], [4]).
