证明了:若M和N是黎曼的n维无边界定向流形,且N是紧的,则有限偏差的Sobolev映射W^{1,n}(M,N)是连续的.特别地,几乎处处具有正Jacobian的$W^{1,n}(M,N)$映射是连续的.这个结果在映射$W^{1,n}(Omega,mathbb{R}^n)$的情况下自1976年以来就已为人所知,其中$Omegasubsetmathbb{R}^n$是一个开集。流形之间的映射的情况要困难得多。
We prove that if $M$ and $N$ are Riemannian, oriented $n$-dimensional manifolds without boundary and additionally $N$ is compact, then Sobolev mappings $W^{1,n}(M,N)$ of finite distortion are continuous. In particular, $W^{1,n}(M,N)$ mappings with almost everywhere positive Jacobian are continuous. This result has been known since 1976 in the case of mappings $W^{1,n}(Omega,mathbb{R}^n)$, where $Omegasubsetmathbb{R}^n$ is an open set. The case of mappings between manifolds is much more difficult.
