 Sandwich theorems for higher-order derivatives of $p$-valent functions defined by certain linear operator Bull. Korean Math. Soc. 2011 Vol. 48, No. 3, 627-636 https://doi.org/10.4134/BKMS.2011.48.3.627Published online May 1, 2011 Mohamed K. Aouf and Tamer M. Seoudy Mansoura University, Fayoum University Abstract : In this paper, we obtain some applications of first order differential subordination and superordination results for higher-order derivatives of $p$-valent functions involving certain linear operator. Some of our results improve and generalize previously known results.
