Graduate Geometry and Topology Learning Seminar

Stacks and moduli spaces

Sumeet Khandelwal - Rutgers University

Location:  Hill room 701
Date & time: Tuesday, 22 March 2022 at 5:15PM - 6:30PM

Abstract: In this talk we will look at stacks. Stacks is a structure that can be used to extend the notion of moduli spaces when objects have non trivial automorphism group and are an analog of orbifolds. In this talk we will primarily look at the space of triangles and how it can be modelled using a stack. We will then see some other examples of stacks.
