Abstract
By making use of the principle of subordination, we introduce a subclass of analytic functions involving generalized Ruscheweyh Derivative operator. The properties such as inclusion relationships, distortion theorems, coefficient inequalities for the above class have been discussed. For analytic functions defined in open unit disc, we establish the differential sandwich theorem.
