复多项式的四点偏差定理

Four-point distortion theorem for complex polynomials

V. N. Dubinin

摘要:

本文证明了一个四点交比在复多项式的映射作用下的畸变定理,该多项式具有限制的临界值。其推论包括涉及多项式的绝对值和某些系数的不等式。特别是,一个确切的下界建立的最大模的临界值的多项式$P$度$n$规范化的$P(0)=0$,$P'(0)\ne0$。

英文摘要:

We prove a theorem on distortion of cross ratio of four points under the mapping effected by a complex polynomial with restricted critical values. Its corollaries include inequalities involving the absolute value and certain coefficients of a polynomial. In particular, an exact lower bound is established for maximal moduli of critical values of polynomials $P$ of degree $n$ normalized by $P(0)=0$, $P'(0)\ne0$.
