Inequalities for a polynomial and its derivative

On the Derivative and Maximum Modulus of a Polynomial

“…If we take K = 1 in the above theorem, we get the following result, which was proved by Aziz and Dawood [1].…”

Generalization of certain well-known inequalities for the derivative of polynomials

“…Aziz and Dawood [1] obtained a refinement of inequality (1.2) by demonstrating that if P (z) is a polynomial of degree n which does not vanish in |z| < 1, then…”

Inequalities for the polar derivative of a polynomial with restricted zeros

“…As a refinement of (1.2), Aziz and Dawood [1] proved that if p(z) is a polynomial of degree n having no zeros in |z| < 1, then…”
