关于一个完全对称函数舒尔凸性的注记

Note on the Schur Convexity of a Completely Symmetric Function

利用Schur凸函数、Schur几何凸函数和Schur调和凸函数的性质,证明了一个完全对称函数的Schur凸性、Schur几何凸性和Schur调和凸性.

By using the properties of Schur-convex function,Schur-geometrically convex function and Schur-harmonically convex function,the Schur-convexity Schur-geometric convexity and Schur-harmonic convexity of a completely symmetric function are proved.
