Abstract:
New classes of multivalent meromorphic functions involving hypergeometric and Koebe functions are introduced,we find some properties of these classes e.g. distortion bounds, radii of starlikeness and convexity, extreme points, Hadamard product and verify effect of some integral operator on members of these classes.

Abstract:
In this paper we introduce the class of functions regular and multivalent in the and satisfying
where
is
a linear operator.
Coefficient inequalities, distortion bounds, weighted mean and
arithmetic mean of functions for this class have been obtained.
