The Fermionic integral on loop space and the Pfaffian line bundle

Florian Hanisch, Matthias Ludewig

As the loop space of a Riemannian manifold is infinite-dimensional, it is a non-trivial problem to make sense of the "top degree component" of a differential form on it. In this pa…

A Rigorous Construction of the Supersymmetric Path Integral Associated to a Compact Spin Manifold

Florian Hanisch, Matthias Ludewig

We give a rigorous construction of the path integral in N=1/2 supersymmetry as an integral map for differential forms on the loop space of a compact spin manifold. It is defined on…

The Trace and the Mass of subcritical GJMS Operators

Matthias Ludewig

Let $L_{g}$ be the subcritical GJMS operator on an even-dimensional compact manifold $(X, g)$ and consider the zeta-regularized trace $Tr_{ζ} (L_{g}^{- 1})$ of its inverse. We sho…
