Topology and Geometry Seminar

Wed., Jan. 31, 2024 12:30 p.m.

Location: CL 251

Speaker: Martin Frankland, University of Regina

Title: Deformation functors

Abstract:  

In the previous talk, we got comfortable with the category of Artin local rings. In this second part, we will move on to functors of Artin rings, deformation functors, and some examples. Time permitting, we will discuss Schlessinger's theorem, giving conditions for a deformation functor to be well approximated by a pro-representable one.
