A note on non singular Einstein-Aether cosmologies

Understand

An effective Lagrangian approach based on an extended Einstein-Aether (EA) model is presented and formulated in a generic non flat Fridman-Lemaitre-Robertson-Walker (FLRW) space-time.

• For a flat FLRW space-time, a Friedmann equation similar to the one obtained in Quantum Loop Cosmology (QLC) is reproduced, with related non singular bounce solution.
• Finally, the Static Spherically Symmetric (SSS) solutions are investigated.
