The fifteenth cohomology group of moduli spaces of stable curves

Amy Bradford, Aitor Iribar López, Andreas Kretschmer +1

The new framework of semi-tautological extensions has allowed for explicit understanding of low-degree odd cohomology groups of moduli spaces of stable curves. Let $S^*_ω(\overline…

Weight decomposition for toroidal abelian fibrations

Younghan Bae, Jeremy Feusi, Aitor Iribar Lopez +1

We study the action of the rational multiplication by $N$ map on the Chow groups of degenerations of principally polarized abelian varieties of torus rank at most one, as well as i…

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…
