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.
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 way that one can easily deduce the results of [5] about division in weighted algebras of analytic func-tions on the unit disc.
