Abstract. The purpose of the present paper is to make use of the familiar concept of neighborhoods of analytic functions. Several inclusion relations associated with the (n, δ) neighborhoods of various subclasses defined by Sălăgean operator are proved. Special cases of these results are shown to yield known results in the literature.
Keywords: neighborhoods; Sălăgean operator.
