具有规定内、外几何视界的黑洞初始数据

Black hole initial data with a horizon of prescribed intrinsic and extrinsic geometry

Brian Smith

摘要:

本工作的目的是构造渐近平坦的,时间对称的初始数据与规定的内在和外在几何的表观地平线。为此,我们使用抛物型偏微分方程来规定标量曲率。在这个方程中,视界几何包含在度量的可自由指定的部分中。这与共形方法形成对比,在共形方法中,视界的几何形状只能指定到一个共形因子。

英文摘要:

The purpose of this work is to construct asymptotically flat, time symmetric initial data with an apparent horizon of prescribed intrinsic and extrinsic geometry. To do this, we use the parabolic partial differential equation for prescribing scalar curvature. In this equation the horizon geometry is contained within the freely specifiable part of the metric. This contrasts with the conformal method in which the geometry of the horizon can only be specified up to a conformal factor.
