准局域瞬时电荷在空间无穷远处的渐近性

Quasi-local instantaneous charges asymptotics at spatial infinity

Jacek Jezierski, Tomasz Smołka

摘要:

本文旨在分析重力场(3+1)分解中电荷(守恒量)的构造。该构造是基于共形Yano Killing(CYK)二形式的(3+1)分裂。分裂导致电荷,定义在柯西表面上,其由Weyl张量和共形Killing矢量的分量组合而成。重新讨论了守恒量与经典ADM守恒量之间的关系。描述了守恒量的渐近行为。分析的费用为一个特定的选择的初始数据,其中包括鲍文-约克旋转黑洞。

英文摘要:

The article aims to analyze a construction of charges (conserved quantities) for the gravity field in the (3+1) decomposition. The construction is based on (3+1) splitting of conformal Yano--Killing (CYK) two-form. The splitting leads to charges, defined on Cauchy surface, which are combined from components of Weyl tensor and conformal Killing vector. The relations between the conserved quantities and its classical ADM counterparts are revisited. Asymptotic behavior of the conserved quantities is described. The charges are analyzed for a particular choice of initial data, among others, Bowen -- York spinning black hole.
