摘要:

我们考虑广义相对论与宇宙学常数最低限度地耦合到电磁场,并假设四维时空流形是一个扭曲的产品的两个表面与洛伦兹和欧几里德签名度量。场方程意味着至少有一个表面必须是常曲率的,从而导致度规的对称性(“自发对称性出现”)。我们分类的情况下,当洛伦兹曲面是常曲率的所有整体解决方案。这些解对于作用在洛伦兹曲面上的洛伦兹SO(1,2)或庞加莱IO(1,1)群是不变的。

英文摘要:

We consider general relativity with cosmological constant minimally coupled to the electromagnetic field and assume that the four-dimensional space-time manifold is a warped product of two surfaces with Lorentzian and Euclidean signature metrics. Field equations imply that at least one of the surfaces must be of constant curvature leading to the symmetry of the metric (``spontaneous symmetry emergence''). We classify all global solutions in the case when the Lorentzian surface is of constant curvature. These solutions are invariant with respect to the Lorentz SO(1,2) or Poincare IO(1,1) groups acting on the Lorentzian surface.
