Fourth-order differential subordination and superordination results of meromorphic multivalent functions defined by multiplier transformation

In this paper, we obtain some applications of fourth-order differential subordination and superordination results involving multiplier transformation H_p (\tau,\psi), for p-valent functions. Also, we obtain several sandwich-type results.
