Dirac型非极小磁单极子作为审查猜想的实现
Non-minimal monopoles of the Dirac type as realization of the censorship conjecture
摘要:
本文讨论了一类三参数非极小扩展Einstein-Maxwell模型的精确解,它是由非极小Dirac型磁单极子引起的。我们着重研究了中心点奇点隐藏在事件视界内的狄拉克磁单极子的引力场,它与物体的质量和电荷无关。得到了满足这一要求的非最小耦合常数之间的关系。作为明确的例子,我们详细考虑了两个单参数模型:第一,非最小扩展Reissner-Nordström模型(磁荷电子),第二,Drummond-Hathrell模型。
英文摘要:
We discuss a class of exact solutions of a three-parameter non-minimally extended Einstein-Maxwell model, which are attributed to non-minimal magnetic monopoles of the Dirac type. We focus on the investigation of the gravitational field of Dirac monopoles for those models, for which the singularity at the central point is hidden inside of an event horizon independently on the mass and charge of the object. We obtained the relationships between the non-minimal coupling constants, for which this requirement is satisfied. As explicit examples, we consider in detail two one-parameter models: first, non-minimally extended Reissner-Nordström model (for the magnetically charged monopole), second, the Drummond-Hathrell model.
