Classes of analytic functions related to the Dziok–Srivastava operator

Abstract

Making use of the Dziok–Srivastava operator, we introduce two classes of analytic functions and investigate convolution properties of these classes. Using convolution properties, we find the necessary and sufficient condition, coefficient estimate and inclusion properties of them.
