E. Minguzzi

AI总结:

该研究刻画了可恰当等距嵌入闵可夫斯基时空的洛伦兹流形,证明可恰当共形嵌入的这类流形等价于全局双曲时空,并借助嵌入得到距离公式的无穷小版本。

摘要:

本文刻画了可恰当等距嵌入闵可夫斯基时空的洛伦兹流形(即同时为闭子集的闵可夫斯基时空洛伦兹子流形)。此外,证明了可恰当共形嵌入闵可夫斯基时空的洛伦兹流形与全局双曲时空等价。最后,利用该嵌入得到了距离公式的无穷小版本。

英文摘要:

I characterize the Lorentzian manifolds properly isometrically embeddable in Minkowski spacetime (i.e. the Lorentzian submanifolds of Minkowski spacetime that are also closed subsets). Moreover, I prove that the Lorentzian manifolds that can be properly conformally embedded in Minkowski spacetime coincide with the globally hyperbolic spacetimes. Finally, by taking advantage of the embedding, I obtain an infinitesimal version of the distance formula.
