摘要

利用哈密顿方法引入准局部质量并对其进行分析。它基于拓扑球体表面的多极分解。在上述模型的基础上，对克尔时空进行了刚性球和圆球两种任意选择表面的试验。该模型预测了总质量的上限和下限。

Quasi-local mass on rigid or round spheres in Kerr spacetime

We introduce and analyze quasi-local mass using Hamiltonian methods. It is based on multipole decomposition for surfaces that are topological spheres. Based on the above model, tests were performed for Kerr spacetime for two arbitrary choices of surfaces: rigid spheres and round spheres. The model predicts upper and lower bounds on the total mass.

期刊介绍： Annals of Physics presents original work in all areas of basic theoretic physics research. Ideas are developed and fully explored, and thorough treatment is given to first principles and ultimate applications. Annals of Physics emphasizes clarity and intelligibility in the articles it publishes, thus making them as accessible as possible. Readers familiar with recent developments in the field are provided with sufficient detail and background to follow the arguments and understand their significance. The Editors of the journal cover all fields of theoretical physics. Articles published in the journal are typically longer than 20 pages.
