摘要:We study the effective BV quantization theory for chiral deformation of two dimensional conformal field theories. We explain a connection between the quantum master equation and the chiral homology for vertex operator algebras. As an application, we construct correlation functions of the curved beta-gamma system and establish a coupled equation relating to chiral homology groups of chiral differential operators. This construction can be viewed as the vertex algebra analogue of the canonical trace map in algebraic index theory and will lead to an algebraic analogue of elliptic index theory. This talk is based on a joint work with Si Li.
