亚纯函数微分多项式的唯一性

Uniqueness of meromorphic function and differential polynomial

利用Nevanlinna理论研究了亚纯函数微分多项式的唯一性问题.在假没函数的零点和极点的重数至少是s(≥1)的条件下,得到了亚纯函数微分多项式的唯一性定理,推广和改进了文献[3]的结果.

Applying the theory of Nevanlinna, we investigate uniqueness problem of differential polynomial of meromorphic functions under the hypothesis of multiplicity of zeros and poles s （≥ 1）. Uniqueness theorems of meromorphic functions and differential polynomial is obtained, which extended and improved the results of literature [3].
