A new characterization of chord-arc domains
A new characterization of chord-arc domains
We show that if \Omega \subset \mathbb{R}^{n+1} , n\geq 1 , is a uniform domain (also known as a 1-sided NTA domain), i.e., a domain which enjoys interior Corkscrew and Harnack Chain conditions, then uniform rectifiability of the boundary of \Omega implies the existence of exterior corkscrew points at all …
