Conformal welding and Koebe’s theorem
Annals of mathematics, Tome 166 (2007) no. 3, pp. 613-656
It is well known that not every orientation-preserving homeomorphism of the circle to itself is a conformal welding, but in this paper we prove several results which state that every homeomorphism is “almost” a welding in a precise way. The proofs are based on Koebe’s circle domain theorem. We also give a new proof of the well known fact that quasisymmetric maps are conformal weldings.
