Nigel Higson (Penn State) will speak in the algebra seminar next week. We will go out for lunch after the talk. When: Friday Sept 6, 12-1pm Where: Carslaw 275 Title: The Mackey bijection Abstract: The Mackey bijection identifies irreducible, usually infinite-dimensional, representations of a real reductive group G with the irreducible representations of the Cartan motion group associated to G. Since the latter are quite easy to determine, whereas the former are not, the bijection is a statement of some substance. At the present time, the bijection seems to be best viewed from the perspective of analysis, tempered representations, and even C*-algebras (sorry). But the bijection, though proved, is far from fully understood. I shall try to give an introduction to the topic that is suitable for an algebra seminar.
