On a Subclass of Univalent Functions Defined by Multiplier Transformations

In the present paper, we introduce a subclass of univalent functions with positive coefficients defined by multiplier transformations in the open unit disk U={z ∈ ℂ: |z| 1}. We obtain some geometric properties, like coefficient inequality, closure theorem, neighborhoods for the subclass WA(l,α,m,η,γ_1,γ_2,λ), radii of starlikeness, convexity and close-to-convexity, weighted mean, arithmetic mean, linear combination and integral representation.
