(几乎)极小集的几何性质,特别是正则性,是几何测度论中的一个有趣的问题,文献[2]、[4]、[5]、[8]、[9]、[10]、[19]、[22]都对其进行了研究。肥皂片以及高原问题的解决方案可能是这种最小集的典型例子。在这篇文章中,我们将研究这类集的序列的收敛,并证明了Hausdorff收敛和变倍收敛在由一致规范函数有界的几乎极小集类上重合,我们将看到大量的集,包括Rn中所有紧的C1,1子流形,几乎是极小的。
The geometric properties of (almost) minimal sets, especially the regularity, is an interesting topic in geometric measure theory, which were often studied in the literature, for example [2],[4],[5],[8],[9],[10],[19],[22]. Soap films as well as solutions to Plateau's Problem could be a typical example of such kind of minimal sets. In this paper, we will investigate the convergence of a sequence of such sets, and show that Hausdorff convergence and varifold convergence coincide on the class of almost minimal sets bounded by a uniform gauge function, and we will see that a large amount of sets, including all compact C 1, 1 submanifolds in R n, are almost minimal.
