• Analytic function
• Hadamard product
• differential subordination
• superordination
• linear operator

In this paper we derive some subordination and superordination results for certain p-valent analytic functions in the open unit disc, which are acted upon by a class of a linear operator. Some of our results improve and generalize previously known results.
