n阶导数具有相同小函数的亚纯函数的唯一性

The Unigueness of Meromorphic Functions whose n-th Derivatives Share the Same Small Function

解决了n阶具有公共小函数亚纯函数的唯一性问题 。

We deal with the problem of unigueness of meromorphic functions whose n th derivatives share the same small function and obtain some results that are improvements over some known theorems
