关于Hardy平均的一个不等式及其应用

An inequality involving Hardy's means and its applications

根据最值压缩定理,建立了n个正数的Hardy平均、算术平均和几何平均之间的一个不等式.作为应用,得到了关于Hamy平均和k次初等对称函数的2个不等式.

According to the compressed independent variable theorems,an inequality involving Hardy＇s means,arithmetic means and geometric means is obtained.As its applications,two inequalities involving Hamy＇s means and elementary symmetric function are proved.
