Some subclasses of analytic functions involving the generalized Noor integral operator

In this paper, we define the generalized Noor integral operator I λ p,n(a, b;c) by using convolution. By applying this operator, we introduce some subclasses Kλ p,n(a + 1, b;c;θ;A,B), KKλ p,n(a, b;c;θ;A,B) and Sλ p,n(a, b, c;β;A,B) of analytic functions and study their subordinate relations, inclusion relations, the integral operator, the sufficient conditions for a function to be in the class Sλ p,n(a, b, c;β) and the radius problems. © 2005 Elsevier Inc.
