In the present investigation, by making use of the familiar concept of neighborhoods of analytic and multivalent functions, we derive coefficient bounds and distortion inequalities, associated inclusion relations for the (n, Ξ΄)-neighborhoods of subclasses of analytic and multivalent functions with n
