A unified approach to holomorphic anomaly equations and quantum spectral curves

Abstract

Abstract We present a unified approach to holomorphic anomaly equations and some well-known quantum spectral curves. We develop a formalism of abstract quantum field theory based on the diagrammatics of the Deligne-Mumford moduli spaces $$ {\overline{\mathrm{\mathcal{M}}}}_{g,n} $$ ℳ ¯ g , n and derive a quadratic recursion relation for the abstract free energies in terms of the edge-cutting operators. This abstract quantum field theory can be realized by various choices of a sequence of holomorphic functions or formal power series and suitable propagators, and the realized quantum field theory can be represented by formal Gaussian integrals. Various applications are given.
