โœฆ Synopsis

In this work the author introduces a certain multiplier transformation for meromorphic pvalent functions which are analytic in U * . The object of this work is to give an application of this operator to the differential inequalities.

Using the methods of differential subordination and superordination, sufficient conditions on the integral operator of meromorphic functions in the punctured unit disk for obtaining, respectively, the best dominant and the best subordinant are determined. New Sandwichtype results are also obtained.
