The Isoperimetric Flow and Synthetic Scalar Curvature for Causal Variational Principles
Felix Finster, Franz Gmeineder, Margarita Kraus
An isoperimetric flow is introduced in the setting of causal variational principles. Describing the whole space by the support of a minimizing measure, we define an area functional…
The cubic Dirac operator on compact quotients of the oscillator group
Ines Kath, Margarita Kraus
We determine the spectrum of Kostant's cubic Dirac operator on locally symmetric Lorentzian manifolds of the form , where is the fo…
Construction of Global Solutions to the Linearized Field Equations for Causal Variational Principles
Felix Finster, Margarita Kraus
We give a novel construction of global solutions to the linearized field equations for causal variational principles. The method is to glue together local solutions supported in le…
The Regularized Hadamard Expansion
Felix Finster, Margarita Kraus
A local expansion is proposed for two-point distributions involving an ultraviolet regularization in a four-dimensional globally hyperbolic space-time. The regularization is descri…
Manifolds with vectorial torsion
Ilka Agricola, Margarita Kraus
The present note deals with the properties of metric connections with vectorial torsion on semi-Riemannian manifolds . We show that the -curvature is…
Curvature Estimates in Asymptotically Flat Lorentzian Manifolds
Felix Finster, Margarita Kraus
We consider an asymptotically flat Lorentzian manifold of dimension (1,3). An inequality is derived which bounds the Riemannian curvature tensor in terms of the ADM energy in the g…
