广义相对论中扩展对象的动力学

Dynamics of Extended Objects in General Relativity

Ibrahim Burak Ilhan

摘要:

本文将对牛顿力学中的物体进行质量、动量和应力密度的多极展开。使用这些定义;定义了$N$引力相互作用孤立体的动量、角动量、质心、力和力矩。导出了该系统的运动方程。动量、角动量、质心、力和力矩的定义是在相对论理论中作出的。定义了动力学(引力)骨架,求出了动力学骨架的多极矩,导出了在引力场中运动的试验体的运动方程。除了细节的推导,没有原创性在这篇论文中声称:它是作为一个主题的审查。

英文摘要:

In this thesis, multipole expansions of mass, momentum and stress density will be made for a body in Newtonian mechanics. Using these definitions; momentum, angular momentum, center of mass, force and torque are defined for $N$ gravitationally interacting isolated bodies. Equations of motions of such a system are derived. Definitions of momentum, angular momentum, center of mass, force and torque are made in a relativistic theory. Dynamical (gravitational) skeleton is defined and the multipole moments of the dynamical skeleton are found. Equations of motion for a test body moving in a gravitational field are derived in terms of the multipole moments. Save the details of the derivations, no originality in this thesis is claimed: it is intended as a review of the subject.
