Dienstag, 13.02.2024: Stable cohomology of moduli spaces of hyperelliptic curves on Hirzebruch surfaces

Angelina Zheng (Roma Tre)

In this talk we present the stable cohomology of moduli spaces of genus g hyperelliptic curves, embedded in a Hirzebruch surface. This is done using two different methods. The first one is Gorinov-Vassiliev’s method, which computes the cohomology of complements of discriminants. Similar information on the cohomology of a moduli space can be obtained through point counting over finite fields. We also describe these moduli spaces of embedded hyperelliptic curves in terms of moduli spaces of pointed non-embedded hyperelliptic curves. This is a joint work with Jonas Bergström.
