M. K. Aouf, A. Shamandy, R. M. El-Ashwah, E. E. Ali

In this paper we derive some subordination and superordination results for certain normalized analytic functions in the open unit disc, which are acted upon by a class of extended multiplier transformations. Relevant connections of the results, which are presented in this paper, with various known results are also considered.
