Abstract

We'll review the definitions of gerbes banded by C and quotient stacks.
Then, I'll define canonical and essential dimension, with examples. I'll
prove two results relating essential/canonical dimension of gerbes/quotient
stacks/algebraic groups. I'll finish by briefly explaining how Karpenko and
Merkurjev used these ideas to prove results about the essential dimension
of finite p-groups.
