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…
Inequalities from Lorentz-Finsler norms
Nicusor Minculete, Christian Pfeifer, Nicoleta Voicu
We show that Lorentz-Finsler geometry offers a powerful tool in obtaining inequalities. With this aim, we first point out that a series of famous inequalities such as: the (weighte…
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…
