Inequalities concerning polar derivative of polynomials [PDF]

open access: yes, 2016
In this paper we obtain certain results for the polar derivative of a polynomial \(p(z) = c_nz^n +\sum_{j=\mu}^n c_{n-j}z^{n-j}\), \(1\leq\mu\leq n\), having all its zeros on \(|z| = k\), \(k\leq 1\), which generalizes the results due to Dewan and Mir ...

Inequalities for the polar derivative of a polynomial [PDF]

open access: yesThe Journal of Analysis, 2020
Let P(z) be a polynomial of degree n having all its zeros in $$|z|\le 1$$ , then according to Turan (Compositio Mathematica 7:89–95, 2004) $$\begin{aligned} \max \limits _{|Z|=1}|P'(z)|\ge ...

Bernstein-Type Inequalities Involving Polar Derivative of a Polynomial [PDF]

open access: yes, 2020
In this paper, we extend some polynomial inequalities to the polar derivative of a polynomial having all its zeros inside or outside a circle of radius k, k > 0 and thereby present some compact generalizations and improvements of certain well-known ...

Generalizations of Zygmund-type integral inequalities for the polar derivative of a complex polynomial

open access: yesJournal of Inequalities and Applications, 2020
Some Zygmund-type integral inequalities for the polar derivatives of complex polynomials, inspired by the classical Bernstein-type inequalities that relate the uniform norms of polynomials and their derivatives on the unit circle, are investigated.

On Extremal Properties for the Polar Derivative of Polynomials

open access: yesAnalysis in Theory and Applications, 2011
Summary: If \(p(z)\) is a polynomial of degree \(n\) having all its zeros on \(|z|=k\), \(k\leq 1\), then it is known that \[ \max\limits_{|z|=1}|p'(z)|\leq \frac n {k^{n-1}+k^n}\max\limits_{|z|=1}|p(z)|. \] In this paper, we generalize the above inequality by extending it to the polar derivative of a polynomial of the type \(p(z)=c_nz^n +\sum\limits ...

Deriving polarity from granularity

open access: yesSemantics and Linguistic Theory, 2021
In this paper, we present a way to unify Positive Polarity Items formed with some NP and minimizers, such as lift a finger. The connection is made via granularity properties of the two classes of polarity sensitive expressions. We begin with an observation in Strawson 1974 that the use of some NP involves an inference about the availability of a more ...
