维续引力的大D极限

The large D limit of dimensionally continued gravity

Gaston Giribet

摘要:

在最近的一篇论文[arXiv:1302.6382]中,恩帕兰、铃木和田边研究了时空维数D趋于无穷大的极限中的广义相对论。结果表明,在这样的极限下,理论显著简化。它简化为一种理论,其基本对象,黑洞和黑膜,表现为非相互作用的粒子。在这里,我们考虑一种不同的方式将引力扩展到D维。我们提出了一个特殊的限制尺寸连续的引力,其中黑洞保持其引力相互作用在大D和仍然有熵的质量成正比。讨论了与[arXiv:1302.6382]中考虑的极限的相似性和差异。

英文摘要:

In a recent paper [arXiv:1302.6382] Emparan, Suzuki, and Tanabe studied general relativity in the limit in which the number of spacetime dimensions D tends to infinity. They showed that, in such limit, the theory simplifies notably. It reduces to a theory whose fundamental objects, black holes and black branes, behave as non-interacting particles. Here, we consider a different way of extending gravity to D dimensions. We present a special limit of dimensionally continued gravity in which black holes retain their gravitational interaction at large D and still have entropy proportional to the mass. The similarities and differences with the limit considered in [arXiv:1302.6382] are discussed.
