Introducion to Algebraic Stacks
Fall 2019   Course Information
Math Annex 1118.
Wed 3-4, Thu 2-3
in Math 227.
One semester of algebraic geometry, such as Math 532. Some
familiarity with varieties, in particular the geometry of curves.
This will be an introduction to algebraic stacks.
The first part (maybe 3-4 weeks) will be a very gentle introduction to the ideas of stacks in general. The only prerequisites for this part are some undergraduate topology, and some undergraduate group theory.
The second part (maybe 3-4 weeks) will cover some basic theory of algebraic stacks, leading to the Riemann-Roch theorem for Deligne-Mumford curves.
For the first two parts, we will follow the notes which constitute the first chapter of this volume on Moduli Spaces. (You should have access through the UBC library.)

The material we discuss in the rest of the course will largely depend on audience interest. One possibility is to cover higher stacks.
Your mark will be based on a project. Your project will be determined
jointly by you and the instructor.
