| Abstract: | Strong differential subordination and superordination properties are determined for Phi-like functions in the open unit disk by investigating appropriate classes of admissible functions. New strong differential sandwich-type results are also obtained. |
| Keywords: | strong differential subordination strong differential superordination analytic functions Phi-like functions admissible functions |
