Title: M_{1,2} bar as a weighted blowup of a weighted projective stack.

Abstract: In this talk I will present an explicit description of M_{1,2} bar as a weighted blow-up of a weighted projective stack. I will discuss some of the advantages of the explicit nature of this description, I will introduce some of the tools of equivariant intersection theory and finally I will compute the integral Chow ring of M_{1,2} bar.

The talk will be preceded with a pre-seminar starting at TBA:

Title: Introduction to intersection theory

Abstract: During this pre-talk I will introduce the Chow groups and Chow rings, and compute the Chow group of the blow-up of P2 at a point.

The talk will also be available via Zoom: https://washington.zoom.us/j/689897930
