On Reversing Operator Choi-Davis-Jensen inequality

Seyyed Saeid Hashemi Karouei, Mohammad Sadegh Asgari, Mohsen Shah Hosseini

Published 2021-04-06Version 1

In this paper, we first provide a better estimate of the second inequality in Hermite-Hadamard inequality. Next, we study the reverse of the celebrated Davis-Choi-Jensen's inequality. Our results are employed to establish a new bound for the operator Kantorovich inequality.
