Potential Modularity of K3 surfaces

This post is to report on results of my student Chao Gu who is graduating this (academic) year. If A/F is an abelian surface, then one can associate to A a K3 surface X (the Kummer surface) by blowing up … Continue reading

Picard Groups of Moduli Stacks update

A tiny update on this post. I was chatting with Benson and realized that I may as well ask him directly for a presentation of the mapping class group of a genus two surface. Perhaps unsurprisingly, it can be found … Continue reading

Picard Groups of Moduli Stacks

Here are some algebraic geometry musings related to the last post, most of which is hopefully correct. Everything below is secretly over \mathbf{Z}[1/6] but I think one may as well think about what is happening over \mathbf{C}. Warning: I don’t … Continue reading
