分担小函数的亚纯函数的唯一性问题

Uniqueness of Meromorphic Functions Sharing Small Function

利用Nevanlinna的值分布理论,进一步讨论了两函数的导数具有公共值问题,推广了杨重骏、仪洪勋在涉及小函数的情况下唯一性的一个结论,得到了一个较为理想的结果.

Using Nevanlinna theory of value distribution, the problem of the derivatives shared one value for two meromorphic functions is discussed, which generalized and improved a uniqueness result concerning small function to C. C. Yang and Yi Hongxun.
