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…

Counting surfaces on Calabi-Yau 4-folds II: - correspondence

Younghan Bae, Martijn Kool, Hyeonjun Park

This is the second part in a series of papers on counting surfaces on Calabi-Yau 4-folds. In this paper, we introduce -theoretic inva…

Counting surfaces on Calabi-Yau 4-folds I: Foundations

Younghan Bae, Martijn Kool, Hyeonjun Park

This is the first part in a series of papers on counting surfaces on Calabi-Yau 4-folds. Besides the Hilbert scheme of 2-dimensional subschemes, we introduce \emph{two} types of mo…

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…

Chow rings of stacks of prestable curves I

Younghan Bae, Johannes Schmitt

We study the Chow ring of the moduli stack of prestable curves and define the notion of tautological classes on this stack. We extend formulas for intersection…

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…

Pixton's formula and Abel-Jacobi theory on the Picard stack

Younghan Bae, David Holmes, Rahul Pandharipande +2

Let be a vector of integers with . By partial resolution of the classical Abel-Jacobi map, we construct a universal twisted double ramifica…

Tautological relations for stable maps to a target variety

Younghan Bae

We define tautological relations for the moduli space of stable maps to a target variety. Using the double ramification cycle formula for target varieties of Janda-Pandharipande-Pi…
