具有权弱分担值的差分或微分多项式的亚纯函数的唯一性

The uniqueness of meromorphic functions of the differential or differential polynomial with the weakly weighed sharing value

利用权弱分担的定义以及唯一性理论方法讨论亚纯函数的k阶导数与差分或微分多项式的k阶导数分担值的问题.分析结果表明,当分担"(1,m)"且Θ(∞,f)介于一定范围的情况下,两个函数的k阶导数相等,其中对应不同的m值,n,m需满足不同的不等式.

We mainly use the definition of the weakly weighted sharing and the theory of uniqueness to discuss the problem that the k derivative of meromorphic function and the k derivative of the differential or differential polynomial share one value. The result is that k derivative of the two functions are equal when they share ＂ （ 1, m） ＂ and Θ（∞,f） is in a certain range, and different m value needs to satisfy different inequalities.
