Proper actions on C*-algebras

In 1990, Rieffel formulated the notion of a proper C*-dynamical system (A, G, a). Under reasonable hypotheses, the corresponding reduced crossed product A×a, rG is Morita equivalent to a "generalized fixed point algebra" Aa in the multiplier algebra M(A). In this talk, I will discuss a number of results concerning proper actions and their generalized fixed point algebras. These results are most efficiently stated by showing that our constructions are functorial. This is work in progress with Astrid an Huef and Iain Raeburn.
