Abstract : Making use of a generalized differential operator we introduce some new subclasses of multivalent analytic functions in the open unit disk and investigate their inclusion relationships. Some integral preserving properties of these subclasses are also discussed.
Keywords : multivalent function, convex univalent function, starlike with respect to symmetric points, Hadamard product, subordination, integral operator
