# Dan Edidin: The integral Chow ring of the stack of hyperelliptic Weierstrass points

Tid: To 2021-10-14 kl 15.30 - 16.30

Föreläsare: Dan Edidin (University of Missouri)

Abstract: The stack $$\mathcal{H}_{g,w}$$ of hyperelliptic Weierstrass points is a degree $$2g+2$$ etale cover of the stack $$\mathcal{H}_g$$ of hyperelliptic curves. The integral Chow rings of $$\mathcal{H}_g$$ and $$\mathcal{H}_{g,1}$$ we previously calculated, and in this talk we explain how to calculate the Chow ring of $$\mathcal{H}_{g,w}$$ using a presentation for $$\mathcal{H}_{g,1}$$ given by Pernice. This is joint work with Zhengning Hu.
