GAP Seminar

Speaker: Bing Kwan So, University of Luxembourg

Abstract: In this talk, I shall explain how Lie groupoids are used to define interesting classes of pseudo-differential operators that are adapted to singular objects. I shall highlight how the theory of b-pseudodifferential calculus on manifolds with embedded boundary by Melrose et. al. fits into this framework. Then I shall discuss how some elements in b-pseudodifferential calculus generalize to other examples, in particular that of the Bruhat Poisson structure on the sphere.
