Abstract

In this paper we impose distinct restrictions on the moduli of the zeros of p ( z ) = n ∑ v = 0 a v z v p(z)=∑v=0navzv and investigate the dependence of ∥ p ( R z ) − p ( σ z ) ∥ ‖p(Rz)−p(σz)‖ , R > σ ≥ 1 R>σ≥1 on M α Mα and M α + π Mα+π , where M α = max 1 ≤ k ≤ n | p ( e i ( α + 2 k π ) / n ) | Mα=max1≤k≤n|p(ei(α+2kπ)/n)| and on certain coefficients of p ( z ) p(z) . This paper comprises several results, which in particular yields some classical polynomial inequalities as special cases. Moreover, the problem of estimating p ( 1 − w n ) p(1−wn) , $0<w\leq$ given $p(1)=0$ is considered.
