On q-analogue of Janowski-type starlike functions with respect to symmetric points

open access: yesDemonstratio Mathematica, 2021
The main objective of the present paper is to define a class of qq-starlike functions with respect to symmetric points in circular domain. Some interesting results of these functions have been evaluated in this article.

On fixed point theorem in complete quasi-metric space under F-contraction mapping

open access: yesTikrit Journal of Pure Science, 2019
In this paper, a fixed point theorem under F-contraction mapping was considered and proved in complete quasi-metric space. This theorem was considered by Piri and Kumam in [1].

Paatero’s V(k) space II

open access: yesConcrete Operators, 2022
In this article we continue our investigation of the Paatero space. We prove that the intersection of every Paatero class V(k) with every Hardy space Hp is closed in that Hp and associate singular continuous measures to elements of V(k).

Modified rush venom immunotherapy in dogs with Hymenoptera hypersensitivity

open access: yesVeterinary Dermatology, Volume 34, Issue 6, Page 532-542, December 2023., 2023
Background – Hymenoptera envenomation occurs frequently in people and dogs and can trigger anaphylaxis. Venom immunotherapy (VIT) is the only preventative treatment for Hymenoptera hypersensitivity and is indicated for people with severe adverse reactions to insect stings. Rush VIT is an accelerated VIT induction schedule performed in people.

Bounds for the second Hankel determinant of certain univalent functions [PDF]

open access: yesJournal of Inequalities and Applications, 2013
The estimates for the second Hankel determinant a2a4−a32 of the analytic function f(z)=z+a2z2+a3z3+⋯ , for which either zf′(z)/f(z) or 1+zf″(z)/f′(z) is subordinate to a certain analytic function, are investigated.

Inclusion Properties on a Class of Meromorphic Functions Defined by a Linear Operator

open access: yesJournal of Mathematical and Fundamental Sciences, 2016
In the present paper, we study a certain class of meromorphic univalent functions f(z) dened by the linear operator L(α,β) f (z). The aim of the present paper is to prove some properties for the class Σα,β,kλ;(h) to satisfy the certain subordination ...

COEFFICIENT CONDITIONS FOR HARMONIC CLOSE-TO-CONVEX FUNCTIONS [PDF]

open access: yes, 2012
New sufficient conditions, concerned with the coefficients of harmonic functions $f(z)=h(z)+\bar{g(z)}$ in the open unit disk $\mathbb{U}$ normalized by $f(0)=h(0)=h'(0)-1=0$, for $f(z)$ to be harmonic close-to-convex functions are discussed. Furthermore,
