Abstract

We use a dynamical systems analysis to investigate the future behavior of Einstein-Aether cosmological models with a scalar field coupling to the expansion of the aether and a noninteracting perfect fluid. The stability of the equilibrium solutions are analyzed, and the results are compared with the standard inflationary cosmological solutions and previously studied cosmological Einstein-aether models.
