On an operator preserving inequalities between polynomials

N. A. Rather, Suhail Gulzar

Let $P_{n}$ denote the space of all complex polynomials $P (z) = \sum_{j = 0}^{n} a_{j} z^{j}$ of degree $n$ and $B_{n}$ a family of operators that maps $P_{n}$ …

Inequalities for the polar derivative of a polynomial

N. A. Rather, Suhail Gulzar

Let $P (z)$ be a polynomial of degree $n$ and for any real or complex number $α,$ let $D_{α} P (z) = n P (z) + (α - z) P^{'} (z)$ denote the polar derivative with respect to $α .$ In this…

Integral mean estimates for the polar derivative of a polynomial

N. A. Rather, Suhail Gulzar

Let $P (z)$ be a polynomial of degree $n$ having all zeros in $∣ z ∣ \leq k$ where $k \leq 1,$ then it was proved by Dewan \textit{et al} that for every real or complex number $α$ w…
