Some new refinements of the Young, Hölder, and Minkowski inequalities

We prove and discuss some new refined Hölder inequalities for any p>1 and also a reversed version for 0< p<1 . The key is to use the concepts of superquadraticity, strong convexity, and to first prove the corresponding refinements of the Young and reversed Young inequalities. Refinements of the Minkowski and reversed Minkowski inequalities are also given.
