AI 中文摘要
我们给出了一个显式的三参数环面Einstein-Maxwell引力瞬子族。这些是具有零标量曲率的完备黎曼流形,满足黎曼Einstein-Maxwell方程。我们论证该度量可以延拓到一个具有两个渐近端的空间,其微分同胚于$\mathbb{H}^2 \times S^2$,并在体内部存在一个非坍缩的二循环(bolt)。该全局度量是通过适当延拓由Ovcharenko-Podolsky构造的局部Lorentzian黑洞几何族的解析延拓而产生的。
英文摘要
We present an explicit three-parameter family of toric Einstein-Maxwell gravitational instantons. These are complete Riemannian manifolds with vanishing scalar curvature which satisfy the Riemannian Einstein-Maxwell equations. We argue that the metric can be extended to a space with two asymptotic ends diffeomorphic to $\mathbb{H}^2 \times S^2$ with a non-collapsing two-cycle (bolt) in the bulk. The global metric is produced by suitably extending an analytic continuation of a local family of Lorentzian black hole geometries constructed by Ovcharenko-Podolsky.
