带洞集的Reifenberg参数化
Reifenberg Parameterizations for Sets with Holes
摘要:
本文将Reifenberg的拓扑圆盘定理的证明推广到有洞集的情形,并给出了$E$上存在$d$ -维平面或光滑流形对$E$的双Lipschitz参数化的充分条件.这样的条件用P. Jones数$β_1(x,r)$的平方和表示。特别是,它适用于局部Ahlfors正则的情况下,以提供非常大的块的双Lipschitz图像的$\R^d$。
英文摘要:
We extend the proof of Reifenberg's Topological Disk Theorem to allow the case of sets with holes, and give sufficient conditions on a set $E$ for the existence of a bi-Lipschitz parameterization of $E$ by a $d$-dimensional plane or smooth manifold. Such a condition is expressed in terms of square summability for the P. Jones numbers $β_1(x,r)$. In particular, it applies in the locally Ahlfors-regular case to provide very big pieces of bi-Lipschitz images of $\R^d$.
