Lie Groupoids and Geometric Stacks, Part III

Date Tuesday, April 9, 2019

In this talk, I will conclude this semester's topic by discussing the weak 2-category of Lie groupoids with bibundle morphisms and how this weak 2-category may be embedded into the 2-category of stacks over manifolds. I will also discuss some benefits/applications of viewing Lie groupoids up to Morita equivalence as stacks.
