A talk that I have once given:


about quantization of local prequantum field theory in the context of differential cohomology in a cohesive topos, motivated from the archetyical example of extended geometric quantization of 2d Chern-Simons theory.

Abstract

The first part of the talk indicates how topological local prequantum field theory is naturally presented by higher correspondences in the slice of a cohesive (∞,1)-topos over an ∞-group of units of some E-∞ ring EE. These are correspondences of moduli stacks of fields (spaces of field trajectories) where the correspondence space is equipped with a cocycle in bivariant twisted E-cohomology. The second part of the talk indicates how quantization of such prequantum data is given by pull-push in twisted E-cohomology, sending correspondences to morphisms of EE-∞-modules. This is analogous to how Chow motives yield cocycles in motivic cohomology. The existence condition on the required orientation in generalized cohomology are the quantum anomaly cancellation conditions. Finally we indicate a list of examples of holographic quantization of boundary field theories this way: the Poisson manifold at the boundary of the non-perturbative Poisson sigma-model (2d Chern-Simons theory), the charged particle at the boundary of the open string and the heterotic string at the boundary of the M2-brane.

The first part is joint work with Domenico Fiorenza and Hisham Sati. The second part is joint work with Joost Nuiten.
