本文研究了涉及例外函数的亚纯函数的正规定则.我们利用P-Z引理,采用反证法,得到一个新的正规定则:若亚纯函数族的零点重级均大于等于3,则涉及例外函数的亚纯函数族是正规的.
In this paper, we study the normal criterion of meromorphic functions concerning omitted functions. By using P-Z lemma and the method of proof by contradiction, we obtain a new normal criterion: if the zeros of the families of meromorphic functions are all have multiplicity at least 3, then the families of meromorphic functions concerning omitted functions are normal.
