In this paper, we introduce a class F n λ,p (α, β, γ) of meromorphic multivalent functions in U * = {z : 0 < |z| < 1} by using a differential operator D n λ,p f(z). We obtain coefficient estimates, distortion theorem, radius of convexity, closure theorems and integral transforms for the class F n λ,p (α, β, γ). Several results involving the Hadamard products of functions belonging to the class F n λ,p (α, β, γ) are also derived.
