Quasiconformality of harmonic mappings between Jordan domains
Quasiconformality of harmonic mappings between Jordan domains
Suppose that h is a harmonic mapping of the unit disc onto a C1, ? domain D. Then h is q.c. if and only if it is bi-Lipschitz. In particular, we consider sufficient and necessary conditions in terms of boundary function that h is q.c. We give a review of …
