摘要
首先对K-拟正则调和映照的系数进行估计,进而估计其凸半径;其次,研究系数满足一定条件的调和映照,并给出其相应的精确的凸半径估计.
In this paper,the coefficients of the K-quasi-regular harmonic mapping is estimated and then its convex radius is obtained.Secondly,the accurate estimation of convex radius of harmonic mapping is given,which the coefficients satisfying certain conditions.
