The main object of this paper is to investigate some subordination results of certain subclasses of multivalent analytic functions which are defined by a generalized fractional differintegral operator. Inclusion relations for functions in the class S λ,μ,η p,q (ζ ; A, B) and the images of these functions by the generalized Bernardi-Libera-Livingston integral operator are also considered.
