Quantum cohomology, Hitchin systems, and Fourier--Mukai comparison

Yunfeng Jiang, Hsian-Hua Tseng

Let be the moduli space of stable trace-free rank Higgs bundles over a smooth projective curve with fixed determinant $Λ\in\Pic(C)$ and . We prove that…

Virasoro Constraints for Orbifold Curves

Jianxun Hu, Pengrong Jin, Hua-Zhong Ke +3

We prove the Virasoro constraints for the relative Gromov--Witten theory of all smooth projective effective orbifold curves, allowing relative conditions at ordinary points. The ab…

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 Toda hierarchy for the stationary theory of the tube with negative contact orders

Hsian-Hua Tseng

We construct a master -Toda tau sequence for the stationary relative theory of $(\PP^1,0,\infty)$ with any fixed finite lists of negative contacts. The negative-contact blocks a…

Descendant and Fourier-Mukai equivalences for simple flops

Jiun-Cheng Chen, Hsian-Hua Tseng

For a simple flop , we construct a correspondence between genus descendant Gromov-Witten theories of and . We show that the Fourier-Mukai equivalen…

A note on Virasoro constraints for products

Hsian-Hua Tseng

We study Virasoro constraints for Gromov-Witten theory of a product variety when one factor has semi-simple quantum cohomology.
