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…

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…

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…

Quantum flips I: local model

Yuan-Pin Lee, Hui-Wen Lin, Chin-Lung Wang

We study analytic continuations of quantum cohomology under simple flips along the extremal ray quantum variable . The inverse correspondence $Ψ=…

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…
