The object is to give an overview of the study of Schur-convexity of various means and functions and to contribute to the subject with some new results. First Schur-convexity of the generalized integral and weighted integral quasiarithmetic mean is studied. Relation to some already published results is established and some applications of the extended result are given. Furthermore Schur-convexity of functions connected to the Hermite-Hadamard inequality is investigated. Finally some results on convexity and Schur-convexity involving divided difference are considered. 1. Introduction The property of Schur-convexity and Schur-concavity has invoked the interest of many researchers and numerous papers have been dedicated to the investigation of it. The object of this paper is to present an overview of the results related to the study of Schur-convexity of various means and functions in particular those connected with the
