Abstract: Motivated by moduli theory, we will discuss how invariants like cohomology, K-theory, and motives can be extended to algebraic stacks. We will see how this stacky perspective recovers and enhances the theories of equivariant cohomology and K-theory. YouTube live link: https://youtu.be/ACRKh4eABgk
