摘要:

 给出了在|z|<R中含有零点的解析函数的模的一个下界;其推论推广了[4]的Thm.1,
由此可较易地推出[5]中关于单位圆盘上解析函数的加权代数的可除性问题的结论.

关键词:  解析函数, 模, 下界, 次调和函数

Abstract:

 In this paper,we give a lower bound for the modulus of analytic functions which have zeros is |z|<R; the corollary extends Thm.1 of [4] in such a waythat one can easIly deduce the results of[5] about division in weighted algebras of analytic functions on the unit disc.

Key words:  Analyticfunction, Modulo, Lowerbound, Subharmonicfunction.
