摘要
本文把杨乐关于有限级整函数结合于导数与重值的辐角分布研究中的Borel 方向从ρ(1)级推广到ρ(q)级,并证明了无限级整函数的 Borel 方向的存在.
In this paper,we extend Borel direction from order ρ(1) toρ(q),which Yang Le stu- died about angular distribution of entire function of finite order and their derivatives with multiple values.We prove the existence of Borel direction of entire functions of infinite order.
