Title: The gravitational field of kinetic gases and the accelerated expansion of the universe

Abstract: Kinetic gases provide a statistical description of large number multi-particle systems in terms of a 1-particle distribution function (1PDF) which encodes the dynamics of the system. Classically, the gravitational field of a kinetic gas is derived from the Einstein equations, with an energy momentum tensor that is derived from the 1PDF by averaging over all velocities. Hence, in the coupling between kinetic gases and spacetime geometry (gravity) only some specific aspects of the gas are taken into account, others are lost.
Pseudo-Finsler manifolds generalize pseudo-Riemannian manifolds in a straightforward manner. The geometry of a Finslerian manifold is derived from a general pseudo-norm, analogously to how the geometry of pseudo-Riemannian manifolds is derived from a metric...
