Beurling-Ahlfors扩张的伸张函数的稳定性

On Stability of Dilatation Function of Beurling-Ahlfors Extension

讨论了Beurling Ahlfors扩张的伸张函数依某种边界函数范数的连续性,应用所得到的结果,讨论了在边界函数发生光滑扰动时,Beurling Ahlfors扩张的伸张函数的稳定性问题,给出了相应的误差估计.

In this paper, at the first, continuity of dilatation function of Beurling-Ahlfors extension in the sence of the norm of boundary functionis is discussed, as an application,this paper discass the stability of dilatation function of Beurling-Ahlfors extension,when the smooth perturbation of boundary function occurs,and give the corresponding error estimate.
