In this paper, we obtain some applications of first order differential subordination and superordination results involving certain linear operator and other linear operators for certain normalized analytic functions. Some of our results improve and generalize previously known results.
Keywords: Analytic function, Hadamard product, differential subordination, superordination, linear operator
