Neighborhoods of a Class of Analytic Functions with Negative Coefficients

[摘要] The main object of this paper is to prove several inclusion relations associated with the $(n,delta )$ neighborhoods of various subclasses of starlike and convex functions of complex order by making use of the known concept of neighborhoods of analytic functions. Special cases of some of these inclusion relations are shown to yield known results.
