We investigate specific new subclasses of the function class ? of bi-univalent function defined in the open unit disc, which is connected with quasi-subordination. We find estimates on the Taylor-Maclaurin coefficients |a2| and |a3| for functions in these subclasses. Already pointed out are some documented and new implications of those findings.

In this paper, we derive some results for multivalent analytic functions defined bylinear operator by using differential Subordination and superordination

In the present paper, we obtain some subordination and superordination Resultsinvolving the integral operator for certain normalized analytic functions in theopen unit disk. These results are applied to obtain sandwich results.
