Title:A geometric perspective on induction and restriction in tempered representation theory, 3
Seminar:Noncommutative Geometry Seminar
Speaker:Nigel Higson, Penn State
Abstract:
These talks are about the decomposition of the regular representation of a group like SL(2,R) into its irreducible constituents. The decomposition has both continuous and discrete parts, and more specifically my talk is about the continuous part, which arises through so-called parabolic induction. I'll describe a bimodule construction, due in the C*-algebra context to Pierre Clare, that gives parabolic induction a noncommutative-geometric form. It is also possible to construct an opposite "parabolic restriction" bimodule, and the question of whether the induction and restriction bimodules are adjoint to one another will be my main concern.
