Starlike and convexity properties of q-Bessel-Struve functions

open access: yesDemonstratio Mathematica, 2022
This paper introduces three different normalization associated with the second and third q-Bessel-Struve functions. We use Hadamard factorizations to determine the radii of starlike and convexity of these functions.

Basic and fractional q-calculus and associated Fekete-Szegő problem for p-valently q-starlike functions and p-valently q-convex functions of complex order

open access: yesMiskolc Mathematical Notes, 2019
In this paper, we introduce and study some subclasses of p-valently analytic functions in the open unit disk U by applying the q-derivative operator and the fractional q-derivative operator in conjunction with the principle of subordination between ...

On univalent functions defined by a generalized Sălăgean operator

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 27, Page 1429-1436, 2004., 2004
We introduce a class of univalent functions Rn(λ, α) defined by a new differential operator Dnf(z), n ∈ ℕ0 = {0, 1, 2, …}, where D0f(z) = f(z), D1f(z) = (1 − λ)f(z) + λzf′(z) = Dλf(z), λ ≥ 0, and Dnf(z) = Dλ(Dn−1f(z)). Inclusion relations, extreme points of Rn(λ, α), some convolution properties of functions belonging to Rn(λ, α), and other results are ...

Estimation of coefficient bounds for a subclass of Sakaguchi kind functions mapped onto various domains

open access: yesConcrete Operators, 2023
In this article, we define a new subclass of analytic functions ℛ(t,δ){\mathcal{ {\mathcal R} }}\left(t,\delta ) in the open unit disk D{\mathbb{D}} associated with the petal-shaped domain.

Upper bound of the third Hankel determinant for a class of analytic functions related with lemniscate of Bernoulli

open access: yesJournal of Inequalities and Applications, 2013
In this paper, the upper bound of the Hankel determinant H3(1) for a subclass of analytic functions associated with right half of the lemniscate of Bernoulli (x2+y2)2−2(x2−y2)=0 is investigated. MSC:30C45, 30C50.

The class of functions spirallike with respect to a boundary point

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 40, Page 2133-2143, 2004., 2004
The aim of this paper is to present an analytic characterization of the class of functions δ‐spirallike with respect to a boundary point. The method of proof is based on Julia′s lemma.

Effect of a ceruminolytic ear cleaner on clinical, microbiological and ear canal microbiome evolution in canine erythemato‐ceruminous otitis externa associated with proliferation of Malassezia yeasts

open access: yesVeterinary Dermatology, Volume 36, Issue 5, Page 668-678, October 2025.
Background – Erythemato‐ceruminous otitis externa (ECOE) is commonly associated with Malassezia spp. and microbial imbalance. Hypothesis/Objective – To assess the clinical performance of an ear cleaner in dogs suffering from ECOE associated with Malassezia spp. overgrowth and to measure its impact on the microbiota. Conclusions and Clinical Relevance –

[Retracted] Partial sums of functions of bounded turning

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 1, Page 45-47, 2004., 2004
We determine conditions under which the partial sums of the Libera integral operator of functions of bounded turning are also of bounded turning.
