在这篇文章中,我们研究了弦理论中提出的全息原理是否与广义相对论中的经典原理相对应。我们证明了存在部分对应:至少在包含所有天体物理黑洞时空的真空Petrov D型时空中,包含一个非平凡杀戮张量的情况下,整体引力与零边界上的二维经典共形标量场之间存在一一对应。
In this paper we investigate whether the holographic principle proposed in string theory has a classical counterpart in general relativity theory. We show that there is a partial correspondence: at least in the case of vacuum Petrov type D spacetimes that admit a non-trivial Killing tensor, which encompass all the astrophysical black hole spacetimes, there exists a one-to-one correspondence between gravity in bulk and a 2-dimensional classical conformal scalar field on a null boundary.
