On Erdös-lax inequality concerning polynomials

IA Wani, I Nazir, MI Mir - Filomat, 2022 - doiserbia.nb.rs
Recently Milovanović et al.[Bulletin T. CLIII de l'Acaémie serbe des sciences et des arts-
2020.] proved that if P (z)∈ Pn with no zeros in| z|< k, k≥ 1, then,| P′(z)|≤∥ P∥/2 [n−{n …

Bernstein-type inequalities for a polynomial not vanishing in a disk

A Mir, F Ahmad - Indian Journal of Pure and Applied Mathematics, 2023 - Springer
We establish some Bernstein-type inequalities which are point-wise estimates for the
modulus of the derivative and polar derivative of a polynomial. The obtained results produce …

Note on an inequality of MA Malik

A Mir, A Ahmad, AH Malik - Applicable Analysis and Discrete Mathematics, 2022 - JSTOR
Let P (z):=∑ υ= 0 na υ z υ be a univariate complex coefficient polynomial of degree n. It was
shown by Malik [J London Math Soc, 1 (1969), 57–60] that if P (z) has all its zeros in| z|≤ k …
