In this note we describe some new topological results derived from the modular invariance of certain elliptic operators on loop spaces under the action of SL2(Z). The results include very general rigidity, divisibility and vanishing theorems in topology.

【期刊论文】Mathematical Results Inspired by Physics
刘克峰, Kefeng Liu

I will discuss results of three different types in geometry and topology. (1) General vanishing and rigidity theorems of elliptic genera proved by using modular forms, Kac-Moody algebras and vertex operator algebras. (2) The computations of intersection numbers of the moduli spaces of flat connections on a Riemann surface by using heat kernels. (3) The mirror principle about counting curves in Calabi-Yau and general projective manifolds by using hypergeometric series.

We construct bundles of modules of vertex operator algebras, and prove the rigidity and vanishing theorem for the Dirac operator on loop space twisted by such bundles. This result generalizes many previous results.
