Abstract

Differential subordinations and superordinations results are obtained for certain meromorphic functions in the punctured unit disk which are associated with certain multiplier transformation and These results are obtained by investigating appropriate classes of admissible functions. Sandwichtype results are also obtained.2000 Mathematics Subject Classification. 30C45.
