BECKER, Jochen e POMMERENKE, Christian. On analytic families of conformai maps. Rev.colomb.mat. [online]. 2017, vol.51, n.1, pp.15-19. ISSN 0034-7426. https://doi.org/10.15446/recolma.v51n1.66832.
Let Λ be a domain in ℂ and let ... be meromorphic in We assume that is holomorphic in for fixed z.
The main theorem states: Let Λ 0 be a subdomain of Λ such that f λ is univalent in for . If has a quasiconformal extension to the closure of for one then f λ has a quasiconformal extension for all .
This result is related to a theorem of Mañé, Sad and Sullivan (1983) where the assumptions are however different. The main tool of our proof is the Grunsky inequality for univalent functions.
