Properties of certain subclasses of multivalent analytic functions involving the Dziok–Srivastava operator

Abstract: In this paper, the authors introduce and investigate the various properties of two subclasses and of multivalent analytic functions. In particular, some sufficient conditions for the subclass of analytic functions, argument properties, the growth theorems, distortion theorems and covering theorems are obtained. Some of the results, presented in this paper, would generalize and extend the corresponding results of earlier authors. [Copyright &y& Elsevier]
