Integral operators preserving certain analytic functions

[摘要] The purpose of the present paper is to investigate some integral preserving properties for certain analytic functions in the open unit disk. We also obtain the conditions for close-to-convex functions in a sector. Our results contain some interesting corollaries as the special cases. (C) 2003 Elsevier Inc. All rights reserved.
