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 ...

Unified representation of a certain class of harmonic univalent functions defined by Dziok-Srivastava operator

Le Matematiche, 2014
In this paper, we investigate several properties of the harmonic class defined by the modified Dziok-Sirvastava operator, obtain distortion theorem, extreme points, convolution condition, convex combinations and integral operator for this class.

Some subclasses of meromorphically multivalent functions associated with the Dziok-Srivastava 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.

On the convex combination of the Dziok–Srivastava operator

Applied Mathematics and Computation, 2007
In 1999 Dziok and Srivastava have introduced the following operator \[ H_p(\alpha_1,\dots,\alpha_q; \beta_1,\dots,\beta_s): f(z) \mapsto h_p(\alpha_1,\dots,\alpha_q; \beta_1,\dots,\beta_s; z)\ast f(z) \] with \(h_p(\alpha_1,\dots,\alpha_q; \beta_1,\dots,\beta_s; z) = z^p\cdot _{q}F_{s}(\alpha_1,\ldots,\alpha_q; \beta_1,\dots,\beta_s; z)\) and \(_{q}F_ ...
