Abstract. New class Σ_{λ}(α, β, γ) of univalent meromorphic functions defined by Ruscheweyh derivative in the punctured unit disk U^{*}is introduced. We study several Hadamard product properties. Some results connected to inclusion relations, neighborhoods of the elements of class Σ_{λ}(α, β, γ) and integral operators are obtained.2000 Mathematics Subject Classification:30C45.

Keywords:Meromorphic functions; Ruscheweyh derivative; Hadamard product; Coefficients inequalities; Integral operator; Neighborhood.
