应用Ahlfors覆盖曲面理论,研究了涉及限制值的亚纯函数族的正规定理,得到涉及单叶岛的正规定理和涉及单叶限制值的正规定理,推广了著名的Ahlfors的五岛定理与Nevanlinna五单值定理.
By using the Ahlfors' covering theorem,the normality criteria for a family of meromorphic functions concerning the restricted values is investigated. Some normal theorems concerning the univalent islands and the univalent restricted values are obtained,which extend the famous Ahlfors' five islands theorem and the Nevanlinna's five univalent-valued theorem.
