摘要：

In this paper we obtain some subordination and superordination results for higher-order derivatives of p-valent functions involving a generalized differential operator D-lambda,p,l(n)(f *g)(j) and also we obtain sandwich-type theorems. Connections of the results obtained in this paper with known results are considerate and an example is presented.
