A subclass of harmonic functions with varying arguments defined by Dziok-Srivastava operator

G. Murugusundaramoorthy, Kaliappan Vijaya, Ravinder Krishna Raina (2009)

Archivum Mathematicum

Similarity:

Making use of the Dziok-Srivastava operator, we introduce a new class of complex valued harmonic functions which are orientation preserving and univalent in the open unit disc and are related to uniformly convex functions. We investigate the coefficient bounds, distortion inequalities and extreme points for this generalized class of functions.

On new subclass of analytic functions with respect to symmetric points

Firas Ghanim, Maslina Darus (2009)

Archivum Mathematicum

Similarity:

In the present paper, we obtain coefficient estimates for new subclass of analytic functions with respect to symmetric points. A sufficient condition for a function to belong to this class of function is also obtained.
