摘要:
研究单位圆盘D={z||z|<1}上满足Re{αz［h″(z)+g″(z)］+h’(z)+g’(z)}>0,z∈D,α>0的单叶调和函数f(z)=h(z)+g(z)^-的拟共形性质,对复伸张w(z)=(g’(z))/(h’(z))的模给出最好的最小上界估计,进而给出该类函数到D的余集Dc上的拟共形延拓,并对其复伸张的模给出最好的最小上界估计,改进和推广了2004年Yalcin S等的研究成果.
Abstract:
We study the quasiconformal properties of the univalent harmonic functions f(z)=h(z)+g(z)^- on the unit disk D={z||z|<1} with Re{αz［h″(z)+g″(z)］+h’(z)+g’(z)}>0, z∈D, α>0, and obtain the best upper bound estimation for the module of the dilatation function w(z)=(g’(z))/(h’(z)). Moreover, we construct their harmonic quasiconformal extension functions to the domain Dc of D, and give the best upper bound estimation for the module of their dilatation functions. The results improve and generalize the ones made by Yalcin S, et al in 2004.
