我们使用局部调和坐标来建立关于度量张量具有有限正则性的黎曼流形之间的等距映射的正则性的尖锐结果(例如,是保持器连续的)。我们还讨论了问题的局部平坦性和局部等距嵌入给定的第一和第二基本形式,在有限光滑的背景下。
We use local harmonic coordinates to establish sharp results on the regularity of isometric maps between Riemannian manifolds whose metric tensors have limited regularity (e.g., are Holder continuous). We also discuss the issue of local flatness and of local isometric embedding with given first and second fundamental form, in the context of limited smoothness.
