Silverman, [email protected] Received 25 September 2007; Revised 19 February 2008; Accepted 21 May 2008 Recommended by Dorothy Wallace We derive subordination and superordination results for a family of normalized analytic functions in the open unit disk defined by integral operators. We apply this to obtain sandwich results and generalizations of some known results. Copyright q 2008 S. P. Goyal et al.
