Let A p be the class of functions f(z) which are analytic in the open unit disk U and satisfy z p f ( z ) ≠ 0 ( z ∈ U ) . Also, let S p * ( α ) denotes the subclass of A p consisting of f(z) which are p-valently starlike of order α(0 ≦ α 0. The object of the present paper is to consider some radius properties for f ( z ) ∈ S p * ( α ) such that δ - p f ( δ z ) ∈ U p ( λ ) . 2010 Mathematics Subject Classification: Primary 30C45.
