Özet

By making use of the familiar concept of neighborhoods of analytic functions, the authors prove several inclusion relations associated with the (n, delta)-neighborhoods of various subclasses of starlike and convex functions of complex order. Special cases of some of these inclusion relations are shown to yield known results. (C) 2000 Elsevier Science Ltd. All rights reserved.
