DESCRIPTION:To realize all possible KMS-bundles with multiple parameters o
 n the Jiang&ndash\;Su algebra\, we construct an action of a free group on 
 a (non-simple) rational approximately finite-dimensional (RAF) algebra. Th
 is construction constitutes an application of the current classification t
 heory for simple Z-absorbing C*-algebras. In this setting\, it is natural 
 to consider actions of non-amenable groups and to address the classificati
 on theory of non-simple C*-algebras\, which I will discuss in my talk. We 
 also investigate a generalization of the correspondence between KMS states
  of crossed products and tracial states of the underlying C*-algebra\, in 
 the case of dynamical systems arising from actions of non-abelian groups w
 ith a certain weak Rohlin property.
