Virasoro Recursions for Simplicially Stable Curves with Colliding Markings
You-Cheng Chou, Hsian-Hua Tseng
We study descendant integrals on moduli stacks of simplicially stable curves. For each finite collision complex, we factor the reduction morphism into elementary wall crossings and…
On the -theoretic logarithmic double ramification class
Kamyar Amini, You-Cheng Chou, Leo Herr +3
The logarithmic double ramification cycle is the virtual fundamental class of the locus where a line bundle on a family of curves is fiberwise trivial. We construct a K-theoretic l…
A theory of generalized Lamé curves
You-Cheng Chou, Chin-Lung Wang, Po-Sheng Wu
We study the generalized Lam'e equation (GLE) on an elliptic curve with multiple regular singularities of weights .…
Higher Genus Quantum --theory
You-Cheng Chou, Leo Herr, Y. -P. Lee
We prove genus invariants in quantum -theory are determined by genus zero invariants of a smooth stack in the spirit of K.~Costello's result in Gromov--Witten theory.
Quantum K-invariants and Gopakumar-Vafa invariants II. Calabi-Yau threefolds at genus zero
You-Cheng Chou, Y. -P. Lee
This is the second part of our ongoing project on the relations between Gopakumar-Vafa BPS invariants (GV) and quantum K-theory (QK) on the Calabi--Yau threefolds (CY3). We show th…
Gopakumar-Vafa Invariants = Quantum K-invariants on Calabi-Yau threefolds
You-Cheng Chou, Y. -P. Lee
The main purpose of this article is to discuss a project relating Gopakumar-Vafa invariants to quantum K-invariants on Calabi-Yau threefolds. Results in genus zero, including recen…
Quantum K-invariants and Gopakumar--Vafa invariants I. The quintic threefold
You-Cheng Chou, Y. -P. Lee
We prove a conjecture of Jockers-Mayr and Garoufalidis-Scheidegger, relating genus zero quantum -invariants and Gopakumar--Vafa invariants on the quintic threefold.
The Log Product Formula in quantum -theory
You-Cheng Chou, Leo Herr, Yuan-Pin Lee
We prove a formula expressing the -theoretic log Gromov-Witten invariants of a product of log smooth varieties in terms of the invariants of and . The proof…
Virasoro constraints for moduli of weighted pointed stable curves
You-Cheng Chou, Yuan-Pin Lee
We formulate Virasoro constraints for the generating functions of the intersection numbers on Hassett's moduli of weighted pointed curves and show that they are governed by the KdV…
Generalized Lamé equation with finite monodromy
You-Cheng Chou
In this paper, we study the algebraic form of the symmetric generalized Lamé equations which have finite projective monodromy groups. In particular, we consider equations with …
