关于微分多项式的正规定则

A Normal Criterion Concerning the Differential Polynomials

本文研究了一类微分多项式的亚纯函数的正规定则。我们改进和推广了前人的结论,利用P-Z引理,采用反证法,得到一个新的正规定则。

In this paper, we discuss the normal criterion of meromorphic functions concerning differential polynomials. We have improved and extended the previous conclusions, by using P-Z lemma and the method of proof by contradiction, we obtain a new normal criterion.
