Complex Variables 2019-12-03 v1

Abstract

Let Ω\Omega be an internal chord-arc Jordan domain and φ:SΩ\varphi:\mathbb S\rightarrow\partial\Omega be a homeomorphism. We show that φ\varphi has finite dyadic energy if and only if φ\varphi has a diffeomorphic extension h:DΩh: \mathbb D\rightarrow \Omega which has finite energy.
