Heat Kernel and Resurgence
Si Li, Yong Li, Xinxing Tang
We study the resurgent structure of short--time heat kernel asymptotics from the viewpoint of Picard--Lefschetz theory. For a real analytic Riemannian manifold, we show the heat ke…
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)…
Homotopy Algebras in Higher Spin Theory
Si Li, Keyou Zeng
Motivated by string field theory, we explore various algebraic aspects of higher spin theory and Vasiliev equation in terms of homotopy algebras. We present a systematic study of u…
