论文摘要
我们为带电，静态和球体对称体的Einstein方程的精确解，周围是弦乐和宇宙常数。这对应于Reissner-Nordström（de Sitter）-anti de Sitter黑洞，被弦液包围。讨论了有关地平线和测量运动的一些方面。我们还通过使用一种方法从其对应物静态构造旋转溶液来构造旋转溶液，从而获得了对应于被字符串流体围绕的Kerr-Newman黑洞对应的度量。分析了视野，梯形和测地运动。在这两种情况下，指出了弦乐液的作用。
We obtain an exact solution of Einstein's equations for a charged, static and spherically symmetric body, surrounded by a fluid of strings and with a cosmological constant. This corresponds to the Reissner-Nordström (de Sitter)-Anti de Sitter black hole surrounded by a fluid of strings. Some aspects concerning the horizons and geodesic motion are discussed. We also obtain the metric corresponding to the Kerr-Newman black hole surrounded by a fluid of strings, by using a method to construct the rotating solution from its counterpart static one. The horizons, ergoregions, and geodesic motion are analyzed. In both cases, the role played by the fluid of strings was pointed out.
