论文摘要
我们考虑了在施瓦茨柴尔德黑洞（例如原始裂缝）的作用下，流体的重力崩溃的问题，该问题突然在流体内突然形成。我们假设流体最初是均匀的灰尘。从这种配置开始，我们根据某些假设获得一类指标。我们发现我们获得的度量包括尘土倒塌作为子壳。在讨论了解决方案的一些基本特性之后，我们将更详细地讨论尘埃崩溃的情况。我们发现，根据参数的值，径向和切向压力可能会呈正值或负值。
We consider the problem of gravitational collapse of a fluid under the effect of a Schwarzschild black hole (e.g. a primordial one) that suddenly forms inside the fluid. We assume the fluid initially be a uniform dust. Starting from this configuration we obtain a class of metrics under some assumptions. We find that the metric we obtain includes the dust collapse as a subcase. After discussing some basic properties of the solution, we discuss the case of dust collapse in more detail. We find that the radial and tangential pressures outside the horizon may take positive or negative values depending on the values of the parameters.
