摘要

我们应用在前一篇文章中发展的技术来描述一些有趣的具有锥形奇点的ALF引力瞬子族。特别地，我们完全理解了Chen-Teo度量的5维族，并证明了只有4维亚族可以光滑紧化，使得度量具有圆锥奇点。

About a Family of ALF Instantons with Conical Singularities

We apply the techniques developed in our previous article to describe some interesting families of ALF gravitational instantons with conical singularities. In particular, we completely understand the 5-dimensional family of Chen-Teo metrics and prove that only 4-dimensional subfamilies can be smoothly compactified so that the metric has conical singularities.
