Canonical variational completion and 4D Gauss-Bonnet gravity
Manuel Hohmann, Christian Pfeifer, Nicoleta Voicu
Recently, a proposal to obtain a finite contribution of second derivative order to the gravitational field equations in \(D = 4\) dimensions from a renormalized Gauss-Bonnet term i…
The kinetic gas universe
Manuel Hohmann, Christian Pfeifer, Nicoleta Voicu
A description of many-particle systems, which is more fundamental than the fluid approach, is to consider them as a kinetic gas. In this approach the dynamical variable in which th…
On the non metrizability of Berwald Finsler spacetimes
Andrea Fuster, Sjors Heefer, Christian Pfeifer +1
We investigate whether Szabo's metrizability theorem can be extended to Finsler spaces of indefinite signature. For smooth, positive definite Finsler metrics, this important theore…
Cosmological Finsler Spacetimes
Manuel Hohmann, Christian Pfeifer, Nicoleta Voicu
Applying the cosmological principle to Finsler spacetimes, we identify the Lie Algebra of symmetry generators of spatially homogeneous and isotropic Finsler geometries, thus genera…
Relativistic kinetic gases as direct sources of gravity
Manuel Hohmann, Christian Pfeifer, Nicoleta Voicu
We propose a new model for the description of a gravitating multi particle system, viewed as a kinetic gas. The properties of the, colliding or non-colliding, particles are encoded…
Finsler gravity action from variational completion
Manuel Hohmann, Christian Pfeifer, Nicoleta Voicu
In the attempts to apply Finsler geometry to construct an extension of general relativity, the question about a suitable generalization of the Einstein equations is still under deb…
