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
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
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.

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.

Application of convolution and Dziok-Srivastava linear operators on analytic and p-valent functions [PDF]
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.

In the present paper, we give some applications of first order differential subordination and superordinations to obtain sufficient conditions for normalized analytic functions defined by certain linear operators to be subordinated and superordinated to a given univalent function.

Certain subclasses of analytic functions with varying arguments
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 ...
