Journal ArticleDOI
Finsler geometric extension of Einstein gravity
TL;DR: In this article, an action integral on the unit tangent bundle is constructed for Finsler spacetimes, which are generalizations of Lorentzian metric manifolds and satisfy necessary causality properties.
Journal ArticleDOI
Causal structure and electrodynamics on Finsler spacetimes
TL;DR: In this paper, a new definition of Finsler spacetimes is presented that generalizes Lorentzian metric manifolds and provides consistent background for physics, including geometric objects like the Cartan nonlinear connection and its curvature.
Journal ArticleDOI
Modified teleparallel theories of gravity in symmetric spacetimes
TL;DR: In this paper, the notion of spacetime symmetries known from Cartan geometry to teleparallel geometries is applied to find universal solutions to the anti-symmetric part of the field equations of any teleparalax theory of gravity.
Journal ArticleDOI
Photon sphere and perihelion shift in weak f ( T ) gravity
TL;DR: In this paper, the photon sphere and perihelion shift for weak general relativity perturbations of general relativity were derived for first order teleparallel perturbation of Schwarzschild and Minkowski spacetime geometry.
Journal ArticleDOI
Hamilton geometry: Phase space geometry from modified dispersion relations
Leonardo Barcaroli,Lukas K. Brunkhorst,Giulia Gubitosi,Niccoló Loret,Christian Pfeifer,Christian Pfeifer +5 more
TL;DR: In this paper, the Hamilton geometry of the phase space of particles whose motion is characterized by general dispersion relations is described, and the expressions for the momentum and position dependent curvatures of spacetime and momentum space are given.
