Differential sandwich theorems for higher-order derivatives of p-valent functions involving a generalized differential operator

Abstract

In the present article, we obtain some applications of first order differential subordination, superordination and sandwich results for higher-order derivatives of p-valent functions involving a generalized differential operator. Some of our results improve and generalize previously known results.
