$ε$ -Approximability of Harmonic Functions in $L^{p}$ Implies Uniform Rectifiability

Simon Bortz, Olli Tapiola

Suppose that $Ω \subset R^{n + 1}$ , $n \geq 2$ , is an open set satisfying the corkscrew condition with an $n$ -dimensional ADR boundary, $\partial Ω$ . In this note, we show tha…

Quantitative Fatou Theorems and Uniform Rectifiability

Simon Bortz, Steve Hofmann

We show that a suitable quantitative Fatou Theorem characterizes uniform rectifiability in the codimension 1 case.
