黎曼流形的Reshetnyak刚性

Reshetnyak rigidity for Riemannian manifolds

Raz Kupferman, Cy Maor, Asaf Shachar

摘要:

证明了黎曼流形之间映射的两个刚性定理。首先,证明了两个定向黎曼流形之间的Lipschitz映射$f:M\to N$是等距浸入,且其微分几乎处处是保向等距的.这个定理以前证明了正则性理论的共形映射,我们给出了一个新的,简单的证明,通过推广的皮奥拉身份的余因子运营商。其次,证明了如果存在一个映射序列$f_n:M\to N$,其微分在$L^p$中收敛到保向等距集,则存在一个子序列收敛到等距浸入.这些结果是著名的Liouville(1850)和Reshetnyak(1967)的刚性定理从欧几里得到黎曼的推广。最后,我们描述了这些定理的应用,非欧弹性和收敛的概念的流形。

英文摘要:

We prove two rigidity theorems for maps between Riemannian manifolds. First, we prove that a Lipschitz map $f:M\to N$ between two oriented Riemannian manifolds, whose differential is almost everywhere an orientation-preserving isometry, is an isometric immersion. This theorem was previously proved using regularity theory for conformal maps; we give a new, simple proof, by generalizing the Piola identity for the cofactor operator. Second, we prove that if there exists a sequence of mapping $f_n:M\to N$, whose differentials converge in $L^p$ to the set of orientation-preserving isometries, then there exists a subsequence converging to an isometric immersion. These results are generalizations of celebrated rigidity theorems by Liouville (1850) and Reshetnyak (1967) from Euclidean to Riemannian settings. Finally, we describe applications of these theorems to non-Euclidean elasticity and to convergence notions of manifolds.
