UNIVALENCE PRESERVING INTEGRAL OPERATOR DEFINED BY GENERALIZED HYPERGEOMETRIC FUNCTIONS
Ibtisam Aldawish,MASLINA DARUS 경남대학교 기초과학연구소 2018 Nonlinear Functional Analysis and Applications Vol.23 No.3
Let I_μ (f_1, f_2, ...f_l, g_1, g_2, ...g_l)(z) be the integral operator defined by generalized hypergeometric functions where each of the functions f_m and g_m are, respectively, analytic functions in the open unit disk for all m = 1, ..., l. The object of this paper is to obtain several univalence conditions for this integral operator. Our main results contain some interesting corollaries as special cases.

Aldawish, Ibtisam,Darus, Maslina The Kangwon-Kyungki Mathematical Society 2014 한국수학논문집 Vol.22 No.4
In the present paper, we investigate starlikeness conditions for q-differential operator by using the concept of quantum calculus in the unit disk.
STRONG DIFFERENTIAL SUBORDINATION AND SUPERORDINATION OF NEW GENERALIZED DERIVATIVE OPERATOR
OSHAH, ANESSA,DARUS, MASLINA The Kangwon-Kyungki Mathematical Society 2015 한국수학논문집 Vol.23 No.4
In this work, certain classes of admissible functions are considered. Some strong dierential subordination and superordination properties of analytic functions associated with new generalized derivative operator $B^{{\mu},q,s}_{{\lambda}_1,{\lambda}_2,{\ell},d}$ are investigated. New strong dierential sandwich-type results associated with the generalized derivative operator are also given.
Coefficient estimates of classes of q-starlike and q-convex functions
HUDA ALDWEBY,MASLINA DARUS 장전수학회 2016 Advanced Studies in Contemporary Mathematics Vol.26 No.1
In this paper, we introduce new classes of q-starlike and q-convex functions involving the q-derivative operator defined on the open unit disk. Furthermore, we obtain estimates on the second and third coefficients of these classes.
Partial sums and neighborhoods of Janowski-type subclasses of meromorphic functions
Abdullah Alatawi,MASLINA DARUS 강원경기수학회 2023 한국수학논문집 Vol.31 No.3
The paper presents the introduction of a novel linear derivative operator for meromorphic functions that are linked with $q$-calculus. Using the linear derivative operator, a new category of meromorphic functions is generated in the paper. We obtain sufficient conditions and show some properties of functions belonging to these subclasses. The partial sums of its sequence and the $q$-neighborhoods problem are solved.
COEFFICIENT BOUNDS FOR CERTAIN SUBCLASSES OF COMPLEX ORDER TYPE β
Anessa Oshah,MASLINA DARUS 경남대학교 기초과학연구소 2018 Nonlinear Functional Analysis and Applications Vol.23 No.4
In the present work, we aim at determine the coefficient bounds for certain subclasses of convex functions of complex order, which are introduced here by means of a family of nonhomogeneous Cauchy-Euler differential equations.
Omar Alnajar,Ala Amourah,MASLINA DARUS 강원경기수학회 2024 한국수학논문집 Vol.32 No.1
In this paper, a new class of bi-univalent functions that are described by Gegenbauer polynomials is presented. We obtain the estimates of the Taylor-Maclaurin coefficients $ \left\vert m_{2}\right\vert $ and $\left\vert m_{3}\right\vert $ for each function in this class of bi-univalent functions. In addition, the Fekete--Szeg\"{o} problems function new are also studied.
Suhila Elhaddad,Huda Aldweby,MASLINA DARUS 경남대학교 기초과학연구소 2018 Nonlinear Functional Analysis and Applications Vol.23 No.4
A new class in the open unit disc of analytic p-valent functions is introduced in this paper. This subclass S^{m,j}_{λ,p}(a_1,b_1,α,β,A,B,γ) is mainly defined by the generalized hypergeometric function. The majorization properties for the functions in this class are introduced. Moreover, we investigate the coefficient estimates for this class.
A few results on Janowski functions associated with $k$-symmetric points
Fuad S Al Sarari,Sridhar Latha,MASLINA DARUS 강원경기수학회 2017 한국수학논문집 Vol.25 No.3
The purpose of the present paper is to introduce and study new subclasses of analytic functions which generalize the classes of Janowski functions with respect to $k$-symmetric points. We also study certain interesting properties like covering theorem, convolution condition, neighborhood results and argument theorem.
