论文摘要
我们考虑静态对称空间的球形对称线性扰动,其中物质含量是元素固定的灰尘。我们表明,流体扰动的演化方程意味着流体元件以恒定速度移动。因此,既没有振荡也没有指数偏离背景解决方案。我们提出了一个明确的例子,该例子表明扰动可能导致黑洞的形成。
We consider spherically symmetric linear perturbations of static spherically symmetric spacetimes where the matter content is ellectrically counterpoised dust. We show that the evolution equation for the fluid perturbation implies that the fluid elements move with constant velocities. Therefore there are neither oscillations nor exponential departure from the background solution. We present an explicit example that shows that the perturbation could lead to the formation of a black hole.
