On Srivastava - Attiya integral operators of certain classes of analytic functions

Abstract

Let S denote the class of functions f analytic in the open unit disc U with normalizations f(0) = 0 = f0(0) – 1. We determine β so that whenever Js,b(f) ∈ S, then Js+1,b(f) ∈ S, for all s ∈ C, b 6= 0,−1,−2,....where Js,b(f) is the Srivastava - Attiya integral operator.
