摘要 The Bloch constants for quasiregular harmonic mappings and open planar harmonic mappings are considered. Better estimates are obtained. The results, presented in this paper, improve the one made by Chen et al. and Grigoryan. The Bloch constants for quasiregular harmonic mappings and open planar harmonic mappings are considered.
