摘要:
若F为单位圆D={z||z|<1}上的双调和映照,L=zz--zz-,即L是一个线性复算子.利用单位圆上有界调和函数的系数估计不等式,对双调和映照L(F)的单叶半径进行估计,所得到的结果优于Chen和Ponnusamy等的结果.
Abstract:
Let F be a biharmonic mapping on the unit disk D,L=zz-,it is a linear complex operator,using the coefficient inequalities for bounded harmonic mappings,we obtain a better univalent radius for biharmonic mappings L(F).Our results improve the one made by Chen and Ponnusamy.
