Strengthened power mean inequalities based on superquadraticity
摘要
The main goal of this paper is a study of more precise power mean inequalities based on a superquadraticity. Our main results lean on a strengthened form of the Jensen inequality that holds for a class of non-negative superquadratic functions. In addition, even more accurate class of power mean inequalities has been established by using the invariance of a variance with respect to the translation. Finally, some generalized power mean inequalities are obtained throughout extension of a concept of superquadraticity, namely so called
