The Euler characteristic of $A_{g}$ via Hodge integrals

Aitor Iribar Lopez

We prove the Harder-Siegel formula for the Euler characteristic of $A_{g}$ via the intersection theory of $M_{g}$ and a vanishing result for lambda class…

The integral Chow ring of $R_{2}$

Alessio Cela, Aitor Iribar Lopez

In this paper we compute the integral Chow ring of the moduli stack $R_{2}$ of Prym pairs of genus 2 with integral coefficients.
