Differential Subordination and Superordination results for certain subclasses of Analytic functions by the technique of admissible functions

Sivasubramanian S


By investigating appropriate classes of admissible functions,  various Differential subordination and superordination results  for analytic functions in the open unit disk  are obtained using Cho-Kwon-Srivastava operator. As a consequence of these results,  Sandwich-type results are also obtained.
