Some applications of fractional integral operators and Ruscheweyh derivatives

Recently, Owa, Saigo, and Srivastava introduced and studied a certain generalized fractional integral operator J(O,Z)(alpha, beta, eta) involving the Gaussian hypergeometric function. The object of this paper is to investigate various properties and relationships involving J(O,Z)(alpha, beta, eta), the Carlson-Shaffer operator L(a, c), and the Ruscheweyh derivative D-lambda. A number of interesting subclasses of analytic and univalent functions are also considered in our investigation. (C) 1996 Academic Press, Inc.
