引力场的拓扑量子化

Topological quantization of gravitational fields

Leonardo Patino, Hernando Quevedo

摘要:

本文系统地介绍了引力场的拓扑量子化方法。首先,我们表明,任何真空解决方案的爱因斯坦方程可以表示在一个主要的纤维丛的连接,在李代数的洛伦兹群的值。这一结果被推广到多主纤维丛中规范物质场的情形。我们提出了几个引力组态的例子,包括在线性化的引力,C-能量的圆柱对称场,Reissner-Nordström和Kerr-Newman黑洞的重力磁引力。由于应用的拓扑量子化程序,在所有的分析的例子中,我们得到的条件意味着在每种情况下进入度量的参数满足一定的离散化关系。

英文摘要:

We introduce the method of topological quantization for gravitational fields in a systematic manner. First we show that any vacuum solution of Einstein's equations can be represented in a principal fiber bundle with a connection that takes values in the Lie algebra of the Lorentz group. This result is generalized to include the case of gauge matter fields in multiple principal fiber bundles. We present several examples of gravitational configurations that include a gravitomagnetic monopole in linearized gravity, the C-energy of cylindrically symmetric fields, the Reissner-Nordström and the Kerr-Newman black holes. As a result of the application of the topological quantization procedure, in all the analyzed examples we obtain conditions implying that the parameters entering the metric in each case satisfy certain discretization relationships.
