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…
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…
Seiberg-Witten differential via primitive forms
Si Li, Dan Xie, Shing-Tung Yau
Three-fold quasi-homogeneous isolated rational singularity is argued to define a four dimensional SCFT. The Seiberg-Witten geometry is built on the mini-versal defo…
Supersymmetric Quantum Mechanics and Lefschetz fixed-point formula
Si Li
We review the explicit derivation of the Gauss-Bonet and Hirzebruch formulae by physical model and give a physical proof of the Lefschetz fixed-point formula by twisting boundary c…
