Starlikeness conditions for an integral operator

Abstract

Let for fixed n ∈ N, σn denotes the class of function of the following form, which are analytic in the punctured open unit disk δ * = {z ∈ c: 0<|z|<1}. In the present paper we defined and studied an operator in for f ∈ σn and c1 - > 0. © 2009 Victoria University. All rights reserved.
