An asymptotically sharp coefficients estimate for harmonic K-quasiconformal mappings
Abstract By using the improved Hübner inequalities, in this paper we obtain an asymptotically sharp lower bound estimate for the coefficients of harmonic K-quasiconformal self-mappings of the unit disk D ${\mathbb{D}}$ which keep the origin fixed. The result partly improves the former results given...
