极端Reissner-Nordström黑洞的波动方程

The wave equation on the extreme Reissner-Nordström black hole

Sergio Dain, Gustavo Dotti

摘要:

本文研究了极端Reissner-Nordström黑洞外开区域上的标量波动方程,证明了在与类时Killing向量场正交的Cauchy曲面上,给定紧支撑的数据,解及其任意阶的$(t,s,θ,ϕ)$导数($s$是一个乌龟径向坐标)都有一个只依赖于初始数据的常数的界.我们的技术不允许研究横向导数在地平线上,这是外面的坐标补丁,我们使用。然而,使用以前的结果表明,第二和更高的横向导数在地平线上的一般解决方案的增长无界沿地平线发电机,我们表明,任何这样的分歧,如果存在的话,将是温和的解决方案与紧凑的初始数据。

英文摘要:

We study the scalar wave equation on the open exterior region of an extreme Reissner-Nordström black hole and prove that, given compactly supported data on a Cauchy surface orthogonal to the timelike Killing vector field, the solution, together with its $(t,s,θ,ϕ)$ derivatives of arbitrary order, $s$ a tortoise radial coordinate, is bounded by a constant that depends only on the initial data. Our technique does not allow to study transverse derivatives at the horizon, which is outside the coordinate patch that we use. However, using previous results that show that second and higher transverse derivatives at the horizon of a generic solution grow unbounded along horizon generators, we show that any such a divergence, if present, would be milder for solutions with compact initial data.
