A Note on Certain Classes of Analytic Functions Defined by Salagean Operator

Abstract. LetA be the class of functions of the form f(z) = z+∑∞m=2 am zm which are analytic in the open unit disk U = {z ∈ C: |z | < 1}. We define the new subclasses M(α, β, n) and M(α, β, n) of analytic functions. The object of the present paper is to derive some convolution properties of functions f in the class M(α, β, n).
