摘要

对于给定的n次多项式p(z)，具有实系数或复系数，我们的基本目标是确定p(z)的所有零所在的最小区域。本文利用拉库纳型多项式得到了一个结果，除了某些特殊情况外，该结果给出了零的区域既不是圆的也不是环的。我们的结果对于减少多项式零区域具有重要的意义。

Location of zeros of a Lacunary type polynomial

For a given polynomial p(z) of degree n with real or complex coefficients, our basic aim has been to determine the smallest region in which all the zeros of p(z) lie. In the present paper, we have obtained a result by using Lacunary type polynomial which gives the region of zeros neither circular nor annular except in some particular cases. Our result plays an important role to reduce the region of polynomial zeros.
