Subordination and Superordination of the Liu-Srivastava Linear Operator on Meromorphic Functions
Rosihan M. Ali, V. Ravichandran and N. Seenivasagan
Abstract.
Using the methods of differential subordination and superordination,
sufficient conditions are determined on the Liu-Srivastava linear operator
of meromorphic functions in the punctured unit disk to obtain respectively the
best dominant and the best subordinant. New sandwich-type results are also
obtained.
