A Cosmological Unicorn Solution to Finsler Gravity
Sjors Heefer, Christian Pfeifer, Antonio Reggio +1
We present a new family of exact vacuum solutions to Pfeifer and Wohlfarth's field equation in Finsler gravity, consisting of Finsler metrics that are Landsbergian but not Berwaldi…
Finsler gravitational waves of -type and their observational signature
Sjors Heefer, Andrea Fuster
We introduce a new class of -type exact solutions in Finsler gravity closely related to the well-known pp-waves in general relativity. Our class contains most of the exact s…
On the metrizability of -Kropina spaces with closed null 1-form
Sjors Heefer, Christian Pfeifer, Jorn van Voorthuizen +1
We investigate the local metrizability of Finsler spaces with -Kropina metric , where is a closed null 1-form. We show that such a space is of Berwald typ…
Randers pp-waves
Sjors Heefer, Christian Pfeifer, Andrea Fuster
In this work we study Randers spacetimes of Berwald type and analyze Pfeifer and Wohlfarth's vacuum field equation of Finsler gravity for this class. We show that in this case the…
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…
Identifying Berwald Finsler Geometries
Christian Pfeifer, Sjors Heefer, Andrea Fuster
Berwald geometries are Finsler geometries close to (pseudo)-Riemannian geometries. We establish a simple first order partial differential equation as necessary and sufficient condi…
