Bipartite-Finsler symmetries

In this work, we study the symmetries of a Lorentz violating bipartite-Finsler spacetime. By using the Finslerian Killing equation for the bipartite-Finsler metric with Lorentzian signature, we analyze how the anisotropy of the bipartite spacetime modifies the local Lorentz symmetries. The symmetries of the pseudo-Finsler metric allow us to obtain the bipartite algebra and interpreted it as a deformed Lorentz algebra. Causality effects driven by the particle modified dispersion relations are investigated upon Minkowski and the Schwarzschild spacetimes. The background bipartite tensor yields to superluminal velocities and modifies the effective gravitational potential. Keywords: Lorentz violation, Finsler metric, Randers space, Dispersion relations
