Abstract

In this paper a certain multiplier operator of p-valent functions is defined. Moreover, subordination- and superordination-preserving properties for a class of multiplier operators defined on the space of normalized analytic functions in the open unit disk is obtained. Also by applying these results, sandwich theorems and generalizations of some known results are obtained.
