In the present article, we determine some subordination and superordination results involving Wanas operator for certain normalized analytic functions defined in the unit disk U. These results are applied to establish sandwich results. Our results extend corresponding previously known results.
Mots-clés : Analytic function, differential subordination, differential superoordination, dominant, subordinant, Wanas operator.
