Birkhoff Theorem for Berwald Finsler spacetimes
Nicoleta Voicu, Christian Pfeifer, Samira Cheraghchi
Finsler spacetime geometry is a canonical extension of Riemannian spacetime geometry. It is based on a general length measure for curves (which does not necessarily arise from a sp…

The Finsler spacetime condition for (α,β)-metrics and their isometries
Nicoleta Voicu, Annamária Friedl-Szász, Elena Popovici-Popescu +1
For the general class of pseudo-Finsler spaces with -metrics, we establish necessary and sufficient conditions such that these admit a Finsler spacetime structure. This mean…
