On the zeros of certain composite polynomials and an operator preserving inequalities

N. A. Rather, Ishfaq Dar, Suhail Gulzar

If all the zeros of $n$ th degree polynomials $f (z)$ and $g (z) = \sum_{k = 0}^{n} I^»_{k} (k n) z^{k}$ respectively lie in the cricular regions $∣ z ∣ \leq r$ and $∣ z ∣ \leq s ∣ z - I ¨ ∣$ , $s>0…

On Visser's inequality concerning coefficient estimates for a polynomial

Suhail Gulzar, N. A. Rather, M. S Wani

If $P (z) = \sum_{j = 0}^{n} a_{j} z^{j}$ is a polynomial of degree $n$ having no zero in $∣ z ∣ < 1,$ then it was recently proved that for every $p \in [0, + \infty]$ and $s = 0, 1, \dots, n - 1,$ \begin{…
