翻译后摘要:我们建立了一个通用的胶合定理的常平均曲率的真空爱因斯坦约束方程的解决方案。 这允许一个连接的总和的解决方案或胶水处理(虫洞)到任何给定的解决方案。远离这个句柄区域,我们生成的初始数据集可以尽可能接近原始的初始数据集。这些构造可以在初始流形是紧的或渐近欧几里得或渐近双曲的情况下进行,并在外部曲率上具有适当的相应条件。在紧的设置一个温和的非退化条件是必需的。在论文的最后一部分,我们列出了这种结构可以用来产生新类型的真空时空的一些方法。
Abstract: We establish a general gluing theorem for constant mean curvature solutions of the vacuum Einstein constraint equations. This allows one to take connected sums of solutions or to glue a handle (wormhole) onto any given solution. Away from this handle region, the initial data sets we produce can be made as close as desired to the original initial data sets. These constructions can be made either when the initial manifold is compact or asymptotically Euclidean or asymptotically hyperbolic, with suitable corresponding conditions on the extrinsic curvature. In the compact setting a mild nondegeneracy condition is required. In the final section of the paper, we list a number ways this construction may be used to produce new types of vacuum spacetimes.
