Journal of Mathematical and Fundamental Sciences, 2015 In this paper, we introduce and investigate a new subclass of bi-univalent functions Σ of complex order dened in the open unit disk, which are associated with hypergeometric functions and satisfying subordinate conditions. Furthermore, we nd estimates on

Inclusion Properties for Classes of p‐Valent Functions
Journal of Function Spaces, Volume 2024, Issue 1, 2024.Making use of a differential operator, which is defined here by means of the Hadamard product, we introduce classes of p‐valent functions and investigate various important inclusion properties and characteristics for these classes. Also, a property preserving integrals is considered.

Subclass of Multivalent Harmonic Functions Defi…ned by Wright Generalized Hypergeometric Functions
Journal of Complex Analysis, Volume 2013, Issue 1, 2013., 2013 We introduce a new class of multivalent harmonic functions defi…ned by Wright generalized hypergeometric function. Coefficient estimates, extreme points, distortion bounds, and convex combination for functions belonging to this class are obtained.

International Journal of Analysis, Volume 2013, Issue 1, 2013., 2013 By making use of the generalized Srivastava‐Owa fractional differential operator, a class of analytical functions is imposed. The sharp bound for the nonlinear functional associated with the Hankel determinant is computed. We consider a new technique to prove our results.

A Class of Starlike Functions Defined by the Dziok-Srivastava Operator
Kyungpook mathematical journal, 2009 Abstract. A comprehensive class of starlike univalent functions de ned by Dziok-Srivastava operator is introduced. Necessary and sucient coecient bounds are givenfor functions in this class to be starlike. Further distortion bounds, extreme points andresults on partial sums are investigated. 1.

Application of convolution and Dziok-Srivastava linear operators on analytic and p-valent functions [PDF]
Filomat, 2006 In this paper, we introduce a new class of multivalent functions defined by convolution and Dziok-Srivastava operator and study some properties of this class e.g. coefficient estimates, integral representation, distortion and closure theorems, convolution and integral operator.

Filomat, 2017 We introduce two new subclasses Hp,k(?,A,B) and Qp,k(?,A,B) of meromorphically multivalent functions associated with the Dziok-Srivastava operator which is a special case of the Srivastava-Wright operator. Distortion inequalities, partial sums and convolutional theorems for Hp,k(?,A,B) and Qp,k(?,A,B) are obtained.

Certain subclasses of analytic functions with varying arguments
Le Matematiche, 2014 In this paper, we introduce new classes VM(β ) and VN(β ) of analytic functions with varying arguments in the open unit disc U = {z ∈ C : |z| <1}. Some properties such as coefficient estimates, extreme points, distortion theorems for functions f (z ...
