Abstract

We review a class of exact solutions of Einstein’s equations in the presence of a scalar field that has three free parameters and become Janis–Newman–Winicour (JNW) metric and γ metric in a certain limit of parameters [1]. We also explain the rotating form of the class of axially symmetric metrics, which contain the rotating gamma and JNW metrics and the Bogush–Gal’tsov (BG) metric at certain values of the parameters [2].

标量场存在时爱因斯坦方程的精确解

我们回顾了爱因斯坦方程在标量场存在下的一类精确解，它们有三个自由参数，在参数的某一极限下成为詹尼斯-纽曼-维尼库尔（JNW）度量和γ度量[1]。我们还解释了一类轴对称度量的旋转形式，其中包含旋转伽马和 JNW 度量，以及在特定参数值下的 Bogush-Gal'tsov (BG) 度量[2]。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
