摘要
本文讨论了有限级亚纯函效及其导数的奇异方向,还讨论了f(z)与f′(z)对较低级的亚纯函数的取值。把杨乐文[1]的结果推广到零级亚纯函数。
In this paper, we study the singular directions of meromorphic functions with finite order and their derivatives, and also study values of meromorphic functions and their derivatives corresponding to meromorphic functions of lower order. We have extended Yang Lo's results to situation of zero order meromorphic functions.
