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…

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…
