正则支撑曲膜

Curved branes with regular support

Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou

摘要:

我们研究了具有满足四维最大对称性的弯曲膜的一般五维膜世界中的时空奇点。体积由理想流体的模拟物支撑,时间由额外的坐标代替。我们表明,相反的存在,从膜的位置在任何解决方案与平坦(闵可夫斯基)膜的有限距离奇点,在弯曲膜的情况下,有奇异自由的解决方案的状态方程的范围内兼容的零能量条件。

英文摘要:

We study spacetime singularities in a general five-dimensional braneworld with curved branes satisfying four-dimensional maximal symmetry. The bulk is supported by an analog of perfect fluid with the time replaced by the extra coordinate. We show that contrary to the existence of finite distance singularities from the brane location in any solution with flat (Minkowski) branes, in the case of curved branes there are singularity-free solutions for a range of equations of state compatible with the null energy condition.
