Title:Pseudodifferential analysis on multiply-fibred manifolds
Seminar:Noncommutative Geometry Seminar
Speaker:Robert Yuncken, Universite Blaise-Pascal, Clermont-Ferrand
Abstract:
Thanks to Connes, we know that the correct analytic structure for studying longitudinal operators on foliated manifolds -- and in particular, on fibre bundles -- is the C*-algebra of the foliation groupoid. In representation theory, however, one encounters manifolds which admit numerous fibrations over different bases, and longitudinal pseudodifferential operators along each of them. In this talk I will discuss the compatibility between the groupoid C*-algebras for such multiply-fibred manifolds, and some applications to index theory.
