零级亚纯函数涉及导数与重值的奇异方向

The Singluar Direction Relate to Derivatives and Multiple Values of Meromorphic Function of Zero Order

应用Ｎｅｖａｎｌｉｎｎａ理论和ＡｈｌｆｏｒｓＳｈｉｍｉｚｕ特征函数理论，得到了满足条件ｌｉｍｒ→＋∞Ｔ（ｒ，ｆ）ｌｏｇ３ｒ＝＋∞的零级亚纯函数涉及导数与重值的奇异方向的存在性。

In this paper applying the theory of Nevanlinna and the theory of Ahlfors Shimizu characteristic functions,the existence of singular direction ralate to derivatives and multiple values of meromorphic function of zero order which satisfies condition lim r→+∞T(r,f) log 3r=+∞ is proven.
