On the exact quantization of BCOV Theory on Calabi-Yau Manifolds

Abstract: We announce the solution of constructing perturbative quantum BCOV invariants on arbitrary Calabi-Yau manifolds. In this note, we outline the construction and present an explicit solution. The quantization includes all descendant fields and all loop orders, and expresses the quantum BCOV interaction by an explicit integration over the moduli space of marked Riemann surfaces. This canonical solution provides a mathematical construction of all higher genus BCOV invariants on compact Calabi-Yau manifolds, which are conjecturally equivalent to all higher genus Gromov-Witten invariants on the mirror.
