Differential Stacks Lecture 1: Introduction to Sheaf Theory
Channel: Stacky Seminar
Date: 2018-10-12

Geoff Vooys (University of Calgary Math) kicks off our seminar series on Differential stacks by introducing sheaf theory.  This lecture covers:
- Pretopologies;
- Grothendieck topologies;
- The equalizer characterization of the sheaf condition.

When you start at the bottom with production quality, it can only get better.
