Pointwise estimates for the derivative of algebraic polynomials
摘要:
给出了点态Bernstein不等式$|P'(z)|\le n|P(z)|$对所有$z\in\overline{\mathbb D}:=\{w\in\mathbb C : |w|\le 1\}$成立的代数多项式$P(z)=\sum_{k=0}^{n}a_kz^k$,$a_n\not=0,$的系数$a_k$的充分条件.
英文摘要:
We give the sufficient condition on coefficients $a_k$ of an algebraic polynomial $P(z)=\sum_{k=0}^{n}a_kz^k$, $a_n\not=0,$ for the pointwise Bernstein inequality $|P'(z)|\le n|P(z)|$ to be true for all $z\in\overline{\mathbb D}:=\{w\in\mathbb C : |w|\le 1\}$.
