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…
