Abstract
In this study, Levinson-type inequalities are generalized by using new Green functions and Montgomery identity for the class of k-convex functions (k ≥ 3). Čebyšev-, Grüss- and Ostrowski-type new bounds are found for the functionals involving data points of two types. Moreover, a new functional is introduced based on
{\mathfrak{f}}
divergence and then some estimates for new functional are obtained. Some inequalities for Shannon entropies are obtained too.
