外部Kerr时空的非线性微扰

The non linear perturbation of the Kerr spacetime in an external region

Giulio Caciotta, Francesco Nicolò

摘要:

我们证明了,在以初始数据超曲面原点为中心的半径为$R_0$的球的影响区域之外,只要初始数据足够接近Kerr时空,Kerr时空附近的整体解的存在性;这个外部区域是扰动Kerr时空外部区域的“远”部分.此外,如果我们假设克尔度规的修正衰减足够快,$o(r^{-3})$,我们证明了黎曼张量的各种零分量的衰减符合“剥离定理”。

英文摘要:

We prove, outside the influence region of a ball of radius $R_0$ centered in the origin of the initial data hypersurface, the existence of global solutions near to Kerr spacetime, provided that the initial data are sufficiently near to those of Kerr; This external region is the "far" part of the outer region of the perturbed Kerr spacetime. Moreover if we assume that the corrections to the Kerr metric decay sufficiently fast, $o(r^{-3})$, we prove that the various null components of the Riemann tensor decay in agreement with the "Peeling theorem".
