有物质存在时静态平面对称时空的局部形式

On the local form of static plane symmetric space-times in the presence of matter

Leandro G. Gomes

摘要:

对于沿时空的静态平面对称分布的物质的任何配置,存在坐标,其中度规可以明确地作为能量密度和压力的函数。它满足爱因斯坦方程,只要我们要求能量动量张量守恒,这是自引力流体静力平衡的唯一常微分方程。作为一个直接的应用,给出了当压力与能量密度线性相关时的一般解,作为特例,恢复了大多数已知的静态平面对称爱因斯坦方程的解.

英文摘要:

For any configuration of a static plane-symmetric distribution of matter along space-time, there are coordinates where the metric can be put explicitly as a functional of the energy density and pressures. It satisfies Einstein equations as far as we require the conservation of the energy-momentum tensor, which is the single ODE for self-gravitating hydrostatic equilibrium. As a direct application, a general solution is given when the pressures are linearly related to the energy density, recovering, as special cases, most of known solutions of static plane-symmetric Einstein equations.
