Dan Edidin - University of Missouri

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