The Gorenstein property and Pixton's conjecture for compact type moduli

Samir Canning, Hannah Larson, Johannes Schmitt

We show that the tautological ring of $M_{g, n}^{ct}$ is not Gorenstein for $g \geq 2$ and $2 g + n \geq 12$ . We prove new cases of Pixton's conjecture that the $3$ -sp…

Samir Canning, Lycka Drakengren, Jeremy Feusi +7

The tautological $Q$ -subalgebra $R^{*} (A_{g}) \subset CH^{*} (A_{g})$ of the Chow ring of the moduli space of principally polarized abelian va…

Extremal descendant integrals on moduli spaces of curves: An inequality discovered and proved in collaboration with AI

Johannes Schmitt

For the pure $I ¨ $ -class intersection numbers $D (e) = ⟨ I ¨ _{e_{1}} \dots I ¨ _{e_{n}} ⟩_{g}$ on the moduli space $M_{g, n}$ of stable curves, we dete…
