Reduced Lagrangians and analytic solutions in Einstein-\ae ther Cosmology

General Relativity and Quantum Cosmology 2019-05-22 v1

Abstract

We present the solution space of the field equations in the Einstein-\ae ther theory for the case of a FLRWFLRW and a LRS Bianchi Type IIIIII space-time. We also find that there are portions of the initial parameters space for which no solution is admitted by the reduced equations. The reduced Lagrangians deduced from the full action are, in general, correctly describing the dynamics whenever solutions do exist
