Abstract

In this paper, making use of the generalized Liu-Srivastava operator, we
introduce and study a new subclass ΣP (α, β, γ, λ, k) of meromorphically univalent functions. We obtain the coefficient estimates, distortion bounds, extreme points, radii of meromorphically starlikeness and convexity for functions in the class ΣP (α, β, γ, λ, k). Furthermore we obtain the partial sums for the same

Keywords and Phrases : Meromorphic functions, Hadamard product (or
convolution), meromorphic starlike functions, meromorphic convex functions,
Liu-Srivastava operator
