Coefficient Estimates and Landau-Bloch's Constant for Planar Harmonic Mappings
Bulletin of the Malaysian Mathematical Society, Tome 34 (2011) no. 2
The aim of this paper is to study the properties of planar harmonic mappings. The main results are as follows. First, by using the subordination of analytic functions, a sharp coefficient estimate is obtained and several applications are given. Then two results about Landau-Bloch's constant are proved: one for planar harmonic mappings and the other for $L(f)$, where $L$ represents the linear complex operator $L=z\frac{\partial}{\partial z} -\overline{z}\frac{\partial}{\partial \overline{z}}$ defined on the class of complex-valued $C^1$ functions in the plane and $f$ is an open harmonic mapping.
