Grothendieck Topologies

Date Friday, January 25, 2019

Grothendieck topologies are, by design, tools which allow one to define sheaves and stacks over entire categories (e.g., the categories of topological spaces or smooth manifolds). In this first talk of the semester, we will fully discuss the definitions of and motivations for Grothendieck (pre)topologies.
