Neighborhood Properties of Certain Classes of Analytic Functions Using the Dziok-Srivastava Operator.

The main object of this paper is to prove several inclusion relations associated with the (n, δ)-neighborhoods of various subclasses of starlike and convex functions of complex order, which are introduced here by means of the Dziok-Srivastava operator. Special cases of some of these inclusion relations are shown to yield known results. [ABSTRACT FROM AUTHOR]
