静态球对称时空的一些注记

Static spherically symmetric space-time: some remarks

Bijan Saha

摘要:

在球对称时空的范围内,我们研究不同类型物质在形成具有球对称性的不同配置中的作用。本文考虑了正压物态方程、标量场、电磁场以及标量场与电磁场相互作用系统作为源的物质。相应的场方程求解利用谐波坐标。提出了一种易于处理的方法,该方法允许人们一旦知道源场的EMT的分量,就对度量函数的可能行为有一个想法。

英文摘要:

Within the scope of a spherically symmetric space-time we study the role of different types of matter in the formation of different configurations with spherical symmetries. Here we have considered matter with barotropic equation of state, scalar field, electromagnetic field and an interacting system of scalar and electromagnetic field as the source. Corresponding field equations are solved exploiting harmonic coordinates. An easy to handle method is proposed which allows one to have an idea about the possible behavior of the metric functions once the components of the EMT of the source field is known.
