# A Framework for Geometric Field Theories and their Classification in Dimension One

@article{Ludewig2021AFF, title={A Framework for Geometric Field Theories and their Classification in Dimension One}, author={Matthias Ludewig and Augusto Stoffel}, journal={Symmetry, Integrability and Geometry: Methods and Applications}, year={2021} }

In this paper, we develop a general framework of geometric functorial field theories, meaning that all bordisms in question are endowed with geometric structures. We take particular care to establish a notion of smooth variation of such geometric structures, so that it makes sense to require the output of our field theory to depend smoothly on the input. We then test our framework on the case of 1-dimensional field theories (with or without orientation) over a manifold M. Here the expectation… Expand

Smooth functorial field theories from B-fields and D-branes

- Mathematics, Physics

In the Lagrangian approach to 2-dimensional sigma models, B-fields and D-branes contribute topological terms to the action of worldsheets of both open and closed strings. We show that these terms… Expand

Connes fusion of spinors on loop space

- Mathematics, Physics

The loop space of a string manifold supports an infinite-dimensional Fock space bundle, which is an analog of the spinor bundle on a spin manifold. This spinor bundle on loop space appears in the… Expand

We show that all extended functorial field theories, both topological and nontopological, are local. Precisely, we show that the functor that sends a target geometry S to the smooth… Expand

This paper proposes a refinement of the usual concept of algebraic quantum field theories (AQFTs) to theories that are smooth in the sense that they assign to every smooth family of spacetimes a… Expand

Smooth one-dimensional topological field theories are vector bundles with connection

We prove that smooth 1-dimensional topological field theories over a manifold are the same as vector bundles with connection. The main novelty is our definition of the smooth 1-dimensional bordism… Expand

Parallel transport of a connection in a smooth fibre bundle yields a functor from the path groupoid of the base manifold into a category that describes the fibres of the bundle. We characterize… Expand

Gerbes and homotopy quantum field theories

For smooth finite dimensional manifolds, we characterise gerbes with connection as functors on a certain surface cobordism category. This allows us to relate gerbes with connection to Turaev's… Expand
