The bielliptic locus in genus 11

Samir Canning, Hannah Larson

The Chow ring of $M_{g}$ is known to be generated by tautological classes for $g \leq 9$ . Meanwhile, the first example of a non-tautological class on $M_{g}$ is t…

The eleventh cohomology group of $M ˉ_{g, n}$

Samir Canning, Hannah Larson, Sam Payne

We prove that the rational cohomology group $H^{11} (M ˉ_{g, n})$ vanishes unless $g = 1$ and $n \geq 11$ . We show furthermore that $H^{k} (M ˉ_{g, n})$ is pu…

On the Chow and cohomology rings of moduli spaces of stable curves

Samir Canning, Hannah Larson

In this paper, we ask: for which $(g, n)$ is the rational Chow or cohomology ring of $M_{g, n}$ generated by tautological classes? This question has been fully…

The rational Chow rings of moduli spaces of hyperelliptic curves with marked points

Samir Canning, Hannah Larson

We determine the rational Chow ring of the moduli space $H_{g, n}$ of $n$ -pointed smooth hyperelliptic curves of genus $g$ when $n \leq 2 g + 6$ . We also show that the Chow r…

The integral Chow rings of moduli of Weierstrass fibrations

Samir Canning, Andrea Di Lorenzo, Giovanni Inchiostro

We compute the Chow rings with integral coefficients of moduli stacks of minimal Weierstrass fibrations over the projective line. For each integer $N \geq 1$ , there is a moduli stac…
