摘要:

本文提出了一种构造动态引力波场模型的恰当时间方法。利用该方法,在Bianchi VI宇宙的特权波坐标系中,构建了强引力波背景下的二次引力波的解析解,作为线性化场方程的扰动解。通过测试粒子的恰当时间关系,得到了二次引力波的度规分量解析形式,并从场方程中获得了包含小修正度规函数的常微分方程及其解。证明了存在一组连续的引力波参数,使得扰动解是稳定的。

英文摘要:

A proper-time method for constructing models of dynamic gravitational-wave fields is presented. Using the proper-time method, analytical (not numerical) models of secondary gravitational waves are constructed as perturbative solutions of linearized field equations against the background of the exact wave solution of Einstein's equations for the vacuum in the Bianchi VI universe in a privileged wave coordinate system. Relations for the proper time of test particles against the background of a strong gravitational wave are used. The analytical form of the metric components for secondary gravitational waves is found from compatibility conditions for the field equations. From the field equations, an explicit form of ordinary differential equations and their solutions is obtained for functions included in small corrections to the metric for secondary gravitational waves. It is shown that there exists a continuum of gravitational wave parameters for which the perturbative solutions are stable.
