Necessary and sufficient coefficient bounds and convolution condition for certain multivalent harmonic functions whose convolution with generalized hypergeometric functions is starlike of order γ are investigated. Results on extreme points, convex combination and distortion bounds using the coefficient condition are also obtained. 2010 Mathematics Subject Classification: 30C45, 30C50

The object of the present paper is to investigate some subordination properties of multivalent analytic functions which are defined here by using the DziokSrivastava operator. Furthermore, relevant connections of the results presented in this paper with those obtained in earlier works are also discussed.

The object of the present paper is to investigate some inclusion relationships and argument properties of several subclasses of multivalent analytic functions, which are defined here by using the Dziok-Srivastava operator. Furthermore, relevant connections of the results presented in this paper with those obtained in earlier works are also pointed out. AMS subject classification: 30C45, 30C50.

In the present paper, we obtain sandwich results involving Hadamard product for certain normalized analytic functions associated with Dziok-Srivastava operator in the open unit disk. Our results extend corresponding previously known results. 2000 Mathematics Subject Classification: Primary 30C45; Secondary 30C80.
