摘要
讨论了初等对称函数差Ek(x)- Ek- 1(x)在n 维单形Ωn= {x= (x1,…,xn)∈Rn+ :E1(x)≤1}和n 维立方体Ω′= {x= (x1,…,xn)∈Rn+ :0≤xi≤1,i= 1,…,n}上的Schur凸性.
In this paper,the Schur convexity of difference for the elementary symmetric functions on n smple Ω n={x 1,…,x n}∈R n +:E 1(x)≤1 and n cube Ω′ n={x=(x 1,…,x n)∈R n +:0≤x i≤1,i=1,…,n} is discussed.
