Homogeneous subsets of a Lipschitz graph and the corona theorem. (English) Zbl 1217.30023

Author’s abstract: “This paper proves the corona theorem for domains in the complex plane bounded by thick subsets of a Lipschitz graph. The boundary \(E_0\) of these domains has a Carleson lower density
\[ \Lambda\big(B(z,r)\cap E_0\big)>\varepsilon_0 r\quad\text{for all}\quad z\in E_0\text{ and } r>0." \]
