引力电磁透镜下的Friedmann-Lemaitre-Robertson-Walker宇宙学
Friedmann-Lemaître-Robertson-Walker cosmology through the lens of gravitoelectromagnetism
摘要：
弗里德曼-勒梅特-罗伯逊-沃克宇宙学是从引力电磁学的观点来考察的，在与哈勃半径相比很小的时空区域的近似中。通常的洛伦兹规范不适合这种情况，而潘勒维-古尔斯特兰德规范则相当自然。几个非平凡的功能和差异方面的“标准”渐近平坦的重力电磁进行了讨论。
英文摘要：
Friedmann-Lemaître-Robertson-Walker cosmology is examined from the point of view of gravitoelectromagnetism, in the approximation of spacetime regions small in comparison with the Hubble radius. The usual Lorentz gauge is not appropriate for this situation, while the Painlevé-Gullstrand gauge is rather natural. Several non-trivial features and differences with respect to "standard" asymptotically flat gravitoelectromagnetism are discussed.
