广义相对论中近日点岁差的同伦微扰解析计算

Analytical Computation of the Perihelion Precession in General Relativity via the Homotopy Perturbation Method

V. K. Shchigolev

摘要:

本文提出用同伦微扰方法(HPM)研究广义相对论中的行星轨道和近日点进动的新方法,并对球对称时空中的非线性测地线方程作了简要的评述。基于HPM的主要思想,我们构造了相应的同伦,从而得到了求解线性方程组的问题。首先,我们考虑史瓦西度规的一个简单例子,它的近似测地线解是已知的,为了比较轨道的HPM解与先前得到的解。此外,我们还得到了带电恒星Reissner-Nordstorm时空的近似HPM解。

英文摘要:

We propose a new approach in studying the planetary orbits and the perihelion precession in General Relativity by means of the Homotopy Perturbation Method (HPM).For this purpose, we give a brief review of the nonlinear geodesic equations in the spherical symmetry spacetime which are to be studied in our work. On the basis of the main idea of HPM, we construct the appropriate homotopy what leads to the problem of solving the set of linear equations. First of all, we consider the simple example of the Schwarzschild metric for which the approximate geodesics solutions are known, in order to compare the HPM solution for orbits with those obtained earlier. Moreover, we obtain an approximate HPM solution for the Reissner-Nordstorm spacetime of a charged star.
