On Fibonacci-type polynomial recurrences of order two and the accumulation points of their set of zeros [PDF]

open access: yes, 2018
We identify the accumulation points of the zero set of the polynomial family Gn+1(z) := zGn(z) + Gn−1(z), n 2 N, generated from complex polynomial seeds G0,G1.

Integral mean estimates for polynomials whose zeros are within a circle

open access: yesJournal of Inequalities and Applications, 2011
Let P(z) be a polynomial of degree n having all its zeros in |z| ≤ K ≤ 1, then for each δ > 0, p > 1, q > 1 with 1 p + 1 q = 1 , Aziz and Ahmad (Glas Mat Ser III 31:229-237, 1996) proved that n ∫ ...

Tolerability and the effect on skin Staphylococcus pseudintermedius density of repeated diluted sodium hypochlorite (bleach) baths at 0.005% in healthy dogs

open access: yesVeterinary Dermatology, Volume 34, Issue 6, Page 489-494, December 2023., 2023
Background – Dilute sodium hypochlorite (bleach) baths at 0.005% concentration twice weekly have been shown to markedly reduce the severity of atopic dermatitis in children, yet no tolerability and efficacy data are available for this treatment in dogs.

Evaluation of the effects of chlorhexidine digluconate with and without cBD103 or cCath against multidrug‐resistant clinical isolates of Staphylococcus pseudintermedius

open access: yesVeterinary Dermatology, Volume 33, Issue 1, Page 17-e6, February 2022., 2022
Background – Because of the increased incidence of multidrug‐resistant (MDR) bacteria, the use of disinfectants over antibiotics has been encouraged. However, the interactions between disinfectants and host local immunity are poorly understood. Objective – To assess the effects of chlorhexidine digluconate (Chx), with and without selected host defence ...

Fluctuations for zeros of Gaussian Taylor series

open access: yesJournal of the London Mathematical Society, Volume 104, Issue 3, Page 1172-1203, October 2021., 2021
Abstract We study fluctuations in the number of zeros of random analytic functions given by a Taylor series whose coefficients are independent complex Gaussians. When the functions are entire, we find sharp bounds for the asymptotic growth rate of the variance of the number of zeros in large disks centered at the origin.

Cosine polynomials with few zeros

open access: yesBulletin of the London Mathematical Society, Volume 53, Issue 3, Page 877-892, June 2021., 2021
Abstract In a celebrated paper, Borwein, Erdélyi, Ferguson and Lockhart constructed cosine polynomials of the form fA(x)=∑a∈Acos(ax),with A⊆N, |A|=n and as few as n5/6+o(1) zeros in [0,2π], thereby disproving an old conjecture of Littlewood. Here we give a sharp analysis of their constructions and, as a result, prove that there exist examples with as ...

Various results in relation with the hypergeometric equations and the hypergeometric functions in the complex plane [PDF]

open access: yes, 2020
The main purpose of this investigation is to specify an extensive relation between the hypergeometric functions and the hypergeometric equations in the complex plane and then to point various implications of our main result, conclusion and also ...

A refinement of an inequality due to Ankeny and Rivlin [PDF]

open access: yes, 2020
Let $p(z)= \sum_{\nu =0}^n a_\nu z^\nu$ be a polynomial of degree $n$, $ M(p,R):= \max_{|z|=R \ge 0} |p(z)|,$ and $M(p,1):=M(p)$. Then by well-known result due to Ankeny and Rivlin \cite{Ankeny}, we have M(p.R)≤(Rn+12)M(p), R≥1. In this paper, we sharpen

Extensions of the Eneström-Kakeya theorem for matrix polynomials

open access: yesSpecial Matrices, 2019
The classical Eneström-Kakeya theorem establishes explicit upper and lower bounds on the zeros of a polynomial with positive coefficients and has been generalized for positive definite matrix polynomials by several authors.

Mean Value Theorems for Analytic Functions [PDF]

open access: yes, 2015
We prove a sharper Evard-Jafari Theorem, various mean value theorems, and an improved version of the Davitt-Powers-Riedel-Sahoo Theorem.
