Strong Differential Sandwich Results of $\lambda$-Pseudo-Starlike Functions with Respect to Symmetrical Points

H. M. Srivastava, Abbas Kareem Wanas

In the present investigation, by considering suitable classes of admissible functions, we establish strong differential subordination and superordination properties for $\lambda$-pseudo-starlike functions with respect to symmetrical points in the open unit disk U. These results are applied to obtain strong differential sandwich results.
