论文摘要

令$ k $为具有绝对值的代数封闭字段。本说明给出了经典结果的基本证明,即多项式($ k $)的多项式根源是多项式系数的连续函数。

Let $K$ be an algebraically closed field with an absolute value. This note gives an elementary proof of the classical result that the roots of a polynomial with coefficients in $K$ are continuous functions of the coefficients of the polynomial.
