我们提出的第一个例子，正式渐近平坦的黑洞解决方案的视野一般透镜空间拓扑结构。这些五维静态或静止时空在事件视界内外都是规则的，对于任何互质整数的选择都是如此;特别是，不存在圆锥奇点。他们支持卡鲁扎-克莱因物质场所产生的高维真空解决方案，通过减少环面。该技术是足够强大的，它导致了明确的建设正规解决方案，在任何维度，实现全方位的可能的拓扑结构的地平线以及域的外部通信，这是允许与多轴对称。最后，作为一个副产品，我们获得了更高维度的规则引力瞬子的新例子。
We present the first examples of formally asymptotically flat black hole solutions with horizons of general lens space topology. These five-dimensional static or stationary spacetimes are regular on and outside the event horizon for any choice of relatively prime integers; in particular, conical singularities are absent. They are supported by Kaluza-Klein matter fields arising from higher dimensional vacuum solutions through reduction on tori. The technique is sufficiently robust that it leads to the explicit construction of regular solutions, in any dimension, realizing the full range of possible topologies for the horizon as well as the domain of outer communication, that are allowable with multi-axisymmetry. Lastly, as a by-product, we obtain new examples of regular gravitational instantons in higher dimensions.
