Some Applications Related to Admissible Functions for Higher-Order Derivatives of Meromorphic Multivalent Functions


Abbas Kareem Wanas, Zainab Swayeh Ghali




In the present manuscript, we obtain some differential subordination and superordination results for higher-order derivatives of meromorphic multivalent functions in the punctured unit disk by investigating appropriate families of admissible functions. These results are applied to obtain differential sandwich results.
