Superquadracity on the coordinates

In 2004 Abramovich, Jameson and Sinnamon introduced a new interesting class of functions: the class of superquadratic functions. Three years later Abramovich, Banić and Matić generalized this concept for the functions in several variables. The class of superquadratic functions is strongly related to the class of convex functions: it can be proved that any nonnegative superquadratic function is convex. The refinements of many important inequalities for convex functions easily follow as special cases when considered superquadratic functions are nonnegative. Here we introduce the class of functions in two variables which are superquadratic on the coordinates. It can be proved that a function which is superquadratic on the coordinates is not necessarily superquadratic and vice versa. The important property of this class of functions is the fact that any nonnegative function superquadratic on the coordinates is also convex on the coordinates. This property enables us to give refinements of some of the previously established results for the functions which are convex on the coordinates. Particularly, we obtain versions of Jensen's and Slater's inequality for functions superquadratic on the coordinates which refine corresponding result obtained by Klaričić Bakula and Pečarić. As an application we use these results to derive several Hölder type inequalities with non conjugate exponents.
