Motivic Euler characteristics of moduli spaces of curves

Jonas Bergström, Samir Canning, Dan Petersen +1

A combination of recent results of Canning--Larson--Payne--Willwacher and Payne--Willwacher is that the motivic Euler characteristic of the moduli space $M_{g, n}$ of nonsingular cu…

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…

The low degree cohomology of compactifications of $A_{g}$

Samir Canning, Dan Petersen, Olivier Taïbi

We compute the low degree $ℓ$ -adic intersection cohomology of symplectic local systems on the Satake compactification of the moduli space $A_{g}$ of principally polarized abelian…

Torelli loci, product cycles, and the homomorphism conjecture for $A_{g}$

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…
