Abstract

Let A be the class of functions f , f (z) = z+ ¥? m=2 amzm, analytic in the open unit disc E. Let S∗ s (h) consist of functions f ∈ A such that 2z f ′(z) f (z)−f (−z) ≺ h(z), where ≺ denotes subordination and h(z) is analytic in E with h(0) = 1. For n = 0,1,2,3, . . . , a certain integral operator In : A→A is defined as In f = f−1 n ∗ f such that ( f−1 n ∗ fn)(z) = z z−1 , where fn(z) = z (1−z)n+1 , and ∗ denotes convolution. By taking h(z) =[1+ 2 p2 􀀀log 1+ √ z 1− √ z )2]a ,0
