abstract

In this paper we introduce the stack of polarized twisted conics and we use it to give a new point of view on $\overline{\mathcal{M}}_2$. In particular, we present a new and independent approach to the computation of the integral Chow ring of $\overline{\mathcal{M}}_2$, previously determined by Eric Larson.

  1. The Integral Chow Rings of the Moduli Stacks of Hyperelliptic Prym Pairs I

    math.AG 2025-01 accept novelty 7.0 of 10

    The integral Chow rings of the moduli stacks RH^1_g and RH^n_g (odd g, 1<n<(g+1)/2) are explicitly computed as quotients of polynomial rings.

  2. Stable maps to quotient stacks with a properly stable point

    math.AG 2024-11 conditional novelty 7.0 of 10

    A new extended weighted blow-up construction yields proper Deligne-Mumford compactifications of stable maps to quotient stacks with projective good moduli space.
