论文摘要
在通用的非平坦Fridman-Lemaitre-Robertson-Walker（FLRW）时空中提出并配制了基于扩展的爱因斯坦 - 乙醚（EA）模型的有效的Lagrangian方法。对于平坦的FLRW时空，使用相关的非单数弹跳溶液再现了类似于量子环宇宙学（QLC）中获得的弗里德曼方程。最后，研究了静态球形对称（SSS）溶液。
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.
