Borel方向与涉及重值的亚纯函数的唯一性
Borel Directions and Uniqueness of Meromorphic Functions Dealing with Multiple Values

利用角域 Nevanlinna 特征函数和亚纯函数的辐角分布理论研究了亚纯函数的角域唯一性问题, 获得了一些涉及重值的角域唯一性的结果,该角域包含亚纯函数的一条 Borel 方向.
The authors study a problem of uniqueness of meromorphic functions in an angular domain containing a Borel direction, and obtain some uniqueness results dealing with multiple values by using the sectorial Nevanlinna characteristic function and the theory of angular distribution of meromorphic functions.
