| 摘 要： | 设ΣH是所有单位圆盘外部Δ*上单叶保向的规范化调和映射。利用Green定理得到了ΣH类的面积定理，并运用该面积定理和Cauchy-Green公式,对具有拟共形延拓性的ΣH类函数的系数进行估计。所得结果推广了经典的Σ类相应结果。

| Abstract: | LetΣH be the class of all sense preserving univalent and normalization harmonic mappings on the exterior of the unit disk Δ*.Using the Green theorem,the area theorem of ΣH was obtained.Then applying this area theorem and Cauchy-Green formula,the coefficients estimation of ΣH with quasiconformal extension to the plane was studied.The results generalize the corresponding results of the classical Σ. |
