  Article:   SUBCLASSES OF HARMONIC FUNCTIONS BASED ON GENERALIZED DERIVATIVE OPERATOR.

Authors:  .
 
       
         
  Abstract:  Making use of Salagean and Ruscheweyh derivative operator we introduced a new class of complex-valued harmonic functions which are orientation preserving, univalent and starlike functions. We investigate the coefficient bounds, distortion inequalities, extreme points and inclusion results for the generalized class of functions.

Key words and phrases. Harmonic univalent starlike functions, extreme points, convolution.
