摘要:We present an effective BV quantization theory for chiral deformation of two dimensional conformal field theories. We introduce a simple procedure (which we call regularized integral) to integrate differential forms with arbitrary holomorphic poles on Riemann surfaces. This gives a geometric renormalization method for 2d chiral quantum field theories. As an application, we construct a vertex algebra analogue of the canonical trace map in algebraic index theory.
