### Abstract

In this paper, a differential operator A_{λ}
^{n}
_{P}(α, β, μ) f(z) defined in the open unit disc U ={z ∈ ℂ : |z| <1} is introduced. We then, using this operator, introduce a new subclass of analytic functions G^{p}
_{n} (α, β, μ, λ, γ, δ). Moreover, we discuss radii of close-to-convexity, starlikeness and convexity. Furthermore, we give an application involving fractional calculus for functions in G^{p}
_{n} (α, β, μ, λ, γ, δ).
