Some subclasses of analytic functions involving the generalized Noor integral operator

摘要

In this paper, we define the generalized Noor integral operator I-p,n(lambda) (a, b; c) by using convolution. By applying this operator, we introduce some subclasses K-p,n(lambda)(a + 1, b; c; theta; A, B), KKp,n lambda, (a, b; c; theta; A, B) and S-p,n(lambda)(a, b, c; beta; 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 S-p,n(lambda)(a, b, c;beta) and the radius problems.
