On the zeros of certain composite polynomials and an operator preserving inequalities
N. A. Rather, Ishfaq Dar, Suhail Gulzar
If all the zeros of th degree polynomials and respectively lie in the cricular regions and , ,…
Inequalities for rational functions with prescribed poles
N. A. Rather, A. Iqbal, Ishfaq Dar
For rational functions, we use simple but elegant techniques to strengthen generalizations of certain results which extend some widely known polynomial inequalities of Erdös-Lax an…
Inequalities for the derivative of Polynomials with restricted zeros
N. A. Rather, Ishfaq Dar, A. Iqbal
In this paper we shall use the boundary Schwarz lemma of Osserman to obtain some generalizations and refinements of some well known results concerning the maximum modulus of the po…
A note on a recent attempt to prove Sendov's conjecture
N. A. Rather, Suhail Gulzar
Recently GM Sofi & SA Shabir [arXive: 1903.01850v2 [math.GM] 6 Mar 2019] made an attempt to prove the Sendov's conjecture. But unfortunately the proof is not correct. In this note,…
Some extensions of Eneström-Kakeya Theorem
N. A. Rather, Suhail Gulzar, S. H. Ahangar
In this paper we obtain some refinements of a well-known result of Eneströ-Kakeya concerning the bounds for the moduli of the zeros of polynomials with complex coefficients which i…
On an inequality concerning the polar derivative of a polynomial with restricted zeros
N. A. Rather, Suhail Gulzar
Let denote the polar derivative of a polynomial of degree with respect to a point In this paper, we present a correc…
