Differential Subordination and Superordination on p-Valent Meromorphic Functions Defined by an Extended Multiplier Transformations

Rabha El-Ashwah, M.K. Aouf

Abstract

In this paper we derive some di¤erential subordination and superordination results for

 

p-valent meromorphic functions in the punctured unit disc, which are acted upon by a class of extended multiplier transformations. These results are obtained by investigating appro-priate classes of admissible functions. Sandwich-type results are also obtained.

Keywords

Meromorphic functions, extended multiplier transformations, sandwich theorems.
