Dispersionless Integrable Hierarchy via Kodaira-Spencer Gravity
Weiqiang He, Si Li, Xinxing Tang +1
We explain how dispersionless integrable hierarchy in 2d topological field theory arises from the Kodaira-Spencer gravity (BCOV theory). The infinitely many commuting Hamiltonians…
Anomaly cancellation in the topological string
Kevin Costello, Si Li
We describe the coupling of holomorphic Chern-Simons theory at large N with Kodaira-Spencer gravity. We explain a new anomaly cancellation mechanism at all loops in perturbation th…
Unfolding of Orbifold LG B-Models: A Case Study
Weiqiang He, Si Li, Yifan Li
In this note we explore the variation of Hodge structures associated to the orbifold Landau-Ginzburg B-model whose superpotential has two variables. We extend the Getzler-Gauss-Man…
On the L2-Hodge theory of Landau-Ginzburg models
Si Li, Hao Wen
Let X be a non-compact Calabi-Yau manifold and f be a holomorphic function on X with compact critical locus. We introduce the notion of f-twisted Sobolev spaces for the pair (X,f)…
