Weight decomposition for toroidal abelian fibrations
Younghan Bae, Jeremy Feusi, Aitor Iribar Lopez +1
We study the action of the rational multiplication by map on the Chow groups of degenerations of principally polarized abelian varieties of torus rank at most one, as well as i…

Chow rings of stacks of prestable curves II
Younghan Bae, Johannes Schmitt
We continue the study of the Chow ring of the moduli stack of prestable curves begun in [arXiv:2012.09887v2]. In genus , we show that the Chow ring of $\mat…

Curves on K3 surfaces in divisibility two
Younghan Bae, Tim-Henrik Buelles
We prove a conjecture of Maulik, Pandharipande, and Thomas expressing the Gromov--Witten invariants of K3 surfaces for divisibility two curve classes in all genus in terms of weakl…
