Some inclusion properties of a certain family of integral operators.
(English)
[J] J. Math. Anal. Appl. 276, No. 1, 432-445 (2002). ISSN 0022-247X

{\it K. I. Noor} [J. Nat. Geom. 16, 71--80 (1999; Zbl 0942.30007)] introduced and studied a new class of integral operators associated with analytic functions. This operator is known as Noor integral operator. In this paper, the authors have considered some new classes of analytic functions defined by the generalized Noor integral operator. Using the standard technique, the authors have studied some inclusion properties of these classes. For recent research work on the Noor integral operator, see {\it K. I. Noor} and {\it M. A. Noor}, J. Math. Anal. Appl. 281, 244--252 (2003; Zbl 1022.30018) and {\it N. E. Cho}, J. Math. Anal. Appl. 283, 202--212 (2003; Zbl 1027.30043)]. Also see {\it K. I. Noor}, N. Z. J. Math. 24, 53--64 (1995; Zbl 0841.30012), where the linear operator was defined using the hypergeometric function.
