与普遍的看法相反,引力理论的渐近反德西特解不能通过在类空表面上取初始数据(满足约束),并在无穷远处的类时边界上选择任意的共形度量来获得。在初始数据面碰到边界的地方,还必须满足无数个角点条件。这些都是众所周知的数学相对主义者,但使他们更广泛地了解,我们给一个简单的解释,为什么这些条件存在,并讨论他们的一些后果。给出了一个例子,说明了他们的权力。全息术的一些影响也提到。
Contrary to popular belief, asymptotically anti-de Sitter solutions of gravitational theories cannot be obtained by taking initial data (satisfying the constraints) on a spacelike surface, and choosing an arbitrary conformal metric on the timelike boundary at infinity. There are an infinite number of corner conditions that also must be satisfied where the initial data surface hits the boundary. These are well known to mathematical relativists, but to make them more widely known we give a simple explanation of why these conditions exist and discuss some of their consequences. An example is given which illustrates their power. Some implications for holography are also mentioned.
