Abstract:

A necessary and sufficient condition for the simplicity of the C$^{*}$–algebra reduced free product of finite dimensional abelian algebras is found, and it is proved that the stable rank of every such free product is 1. Related results about other reduced free products of C$^{*}$–algebras are proved.
