Inclusion Properties of Certain Classes of Meromorphic Functions Associated with the Generalized Hypergeometric Function

Let Σp denote the class of functions normalized by ∞ n=1 anz n−p (p ∈ N ), which are analytic and p-valent in 0 < |z| < 1. Making use of a linear operator, which is defined here by the generalized hypergeometric function, we introduce some new subclasses of the meromorphically p-valent function class Σp and investigate their inclusion relationships.
