Certain Subclasses of Multivalent Analytic Functions

Abstract

Two new subclasses $H_{p,k}(\lambda ,A,B)$ and $Q_{p,k}(\lambda ,A,B)$ of multivalent analytic functions are introduced. Distortion inequalities and inclusion relation for $H_{p,k}(\lambda ,A,B)$ and $Q_{p,k}(\lambda ,A,B)$ are obtained. Some results of the partial sums of functions in these classes are also given.
