Our main result in this article is a compactness result which states that a noncollapsed sequence of asymptotically locally Euclidean (ALE) scalar-flat Kähler metrics on a minimal Kähler surface whose Kähler classes stay in a compact subset of the interior of the Kähler cone must have a convergent subsequence. As an application, we prove the existence of global moduli spaces of scalar-flat Kähler ALE metrics for several infinite families of Kähler ALE spaces.

ALE 标量平坦 KÄHLER 曲面的存在性和紧致性理论

我们在本文中的主要结果是紧致性结果,它表明在最小 Kähler 曲面上的非折叠序列的渐近局部欧几里德 (ALE) 标量平坦 Kähler 度量,其 Kähler 类位于 Kähler 锥内部的紧致子集中必须具有一个收敛的子序列。作为一个应用程序,我们证明了几个无限的 Kähler ALE 空间族的标量平坦 Kähler ALE 度量的全局模空间的存在。
