我们推导出一个时空质量的下限，根据它的电荷和磁荷，这是磁单极子的Bogomolny界的类似物。我们给出了一个几乎完整的表征时空的界限达到，提供明确的多孤子解决方案，并描述它们如何适合超多重态。
We derive a lower bound for the mass of a space-time, in terms of its electric and magnetic charges, which is the analogue of the Bogomolny bound for magnetic monopoles. We give an almost complete characterization of space-times for which the bound is attained, provide explicit multi-soliton solutions and describe how they fit into supermultiplets.
