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 .…
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…
