奇点处的爱因斯坦方程

Einstein equation at singularities

Ovidiu-Cristinel Stoica

摘要:

爱因斯坦方程被改写成一个等价的形式,在某些主要情况下,它在奇点处仍然有效。这些情况包括史瓦西奇点、弗里德曼-勒马特-罗伯逊-沃克大爆炸奇点、各向同性奇点和一类翘曲积奇点。这个方程是根据黎曼曲率的里奇部分(作为爱因斯坦方程和度量张量之间的Kulkarni-Nomizu乘积)构造的。

英文摘要:

Einstein's equation is rewritten in an equivalent form, which remains valid at the singularities in some major cases. These cases include the Schwarzschild singularity, the Friedmann-Lemaître-Robertson-Walker Big Bang singularity, isotropic singularities, and a class of warped product singularities. This equation is constructed in terms of the Ricci part of the Riemann curvature (as the Kulkarni-Nomizu product between Einstein's equation and the metric tensor).
