A New Subclass of Harmonic Univalent Functions Associated with Dziok-Srivastava Operator [PDF]
International Journal of Mathematics and Mathematical Sciences, 2012 The purpose of the present paper is to study a certain subclass of harmonic univalent functions associated with Dziok-Srivastava operator. We obtain coefficient conditions, distortion bounds, and extreme points for the above class of harmonic univalent ...

New Subclasses of Biunivalent Functions Involving Dziok‐Srivastava Operator [PDF]
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 We introduce two new subclasses of biunivalent functions which are defined by using the Dziok‐Srivastava operator. Furthermore, we find estimates on the coefficients |a2| and |a3| for functions in these new subclasses.

Classes of spirallike functions defined by the Dziok-Srivastava operator
Le Matematiche, 2014 Making use of the Dziok-Srivastava operator, we introduce two classes of analytic functions and investigate convolution properties, the necessary and sufficient condition, coefficient estimates and inclusion properties for these classes.

A Subclass of Harmonic Univalent Functions Associated with q‐Analogue of Dziok‐Srivastava Operator [PDF]
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 We study a class of complex‐valued harmonic univalent functions using a generalized operator involving basic hypergeometric function. Precisely, we give a necessary and sufficient coefficient condition for functions in this class. Distortion bounds, extreme points, and neighborhood of such functions are also considered.

Journal of Inequalities and Applications, 2011 Subordination and superordination preserving properties for multivalent functions in the open unit disk associated with the Dziok-Srivastava operator are derived. Sandwich-type theorems for these multivalent functions are also obtained.

A Subclass of Harmonic Functions Related to a Convolution Operator
Journal of Function Spaces, Volume 2016, Issue 1, 2016., 2016 We introduce a new subclass of harmonic functions by using a certain linear operator. For this class we derive coefficient bounds, extreme points, and inclusion results and also show that this class is closed under an integral operator.

Subclasses of Analytic Functions Defined by Generalized Hypergeometric Functions
Journal of Function Spaces, Volume 2016, Issue 1, 2016., 2016 We introduce a new subclass of analytic functions in the unit disk U, defined by using the generalized hypergeometric functions, which extends some previous well‐known classes defined by different authors. Inclusion results, radius problems, and some connections with the Bernardi‐Libera‐Livingston integral operator are discussed.
