Certain estimates of Turán’s-type for the maximum modulus of the polar derivative of a polynomial

open access: yesPublications de l'Institut Math?matique (Belgrade), 2020
We establish some lower bound estimates for the maximum modulus of the polar derivative of a polynomial on the unit disk under the assumption that the polynomial has all zeros in another disk.

On Bernstein-type inequalities for polynomials involving the polar derivative

open access: yesJournal of Classical Analysis, 2020
. In this paper, we establish some upper bound estimates for the polar derivative of a polynomial not vanishing in a disk | z | < k , k (cid:2) 1 with a zero of multiplicity s , 0 (cid:3) s (cid:3) n − 1 at the origin.

Chiroptical Properties and the Racemization of Pyrene and Tetrathiafulvalene-Substituted Allene: Substitution and Solvent Effects on Racemization in Tetrathiafulvalenylallene

open access: yesMolecules, 2014
Dissymmetric 1,3-diphenylallene derivative 3 connected with 4,5-bis(methyl-thio)tetrathiafulvalenyl and 1-pyrenyl substituents was prepared and characterized. The molecular structure was determined by X-ray crystallographic analysis.

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 ...

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 ...

Ichnodiversity in the eastern Canadian Arctic in the context of polar microbioerosion patterns

open access: yes, 2022
Studies of marine microbioerosion in polar environments are scarce. They include our recent investigations of bioerosion traces preserved in sessile balanid skeletons from the Arctic Svalbard archipelago and the Antarctic Ross Sea.

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.
