设 D 为 Rn 中的域,n > 2,f 为 D 上的拟共形映射。我们给出 D 中余维 1 的边界面的定义,并表明,给定系统 2;对于这样的表面,将 f 限制为“几乎每个”表面的图像也是一个表面。此外,在这些表面上,f 将 Hn-1(Hausdorff (n I) 维)零集变为 H 1n 零集。通过测量系统模的概念(极值长度概念的概括),“几乎每个”表面都被赋予了精确的含义。
Let D be a domain in Rn, n > 2, f a quasiconformal mapping on D. We give a definition of bounding surface of codimension one lying in D, and show that, given a system 2; of such surfaces, the image of the restriction of f to "almost every" surface is again a surface. Moreover, on these surfaces, f takes Hn-1 (Hausdorff (n I)-dimensional) null sets to H 1n null sets. "Almost every" surface is given a precise meaning via the concept of the module of a system of measures, a generalization of the concept of extremal length.
