WebMany examples of Schur convex functions can of course be found in the literature. Perhaps the sim-plest example is what is called a separable convex function. It is of the form g(x)= Xn i=1 h(xi), where h is a convex function. We now begin our tour of examples in the liter-ature in which majorization makes cameo and/or starring appearances.
