Oberseminar Deformationsquantisierung und Geometrie: Stefano Ronchi (Göttingen)

Abstract: The cotangent bundle of a manifold is a central object in mathematics and
physics. There is a similar construction for Lie groupoids. In this talk I
will explain how to extend this to Lie n-groupoids and give some
fundamental applications. This is joint work with Miquel Cueca and
Chenchang Zhu.
