Abstract

Extension for Jensen-type inequality and reverse of Jensen’s inequality under the assumption of second-order differential inequality

p(x)f(x)+q(x)f(x)+f(x)0

are established, Hermite–Hadamard-type inequality is also proven. We get some refinements of power mean inequality as applications and further extend normalised Jensen functional under the assumption of second-order differential inequality as an improvement.
