摘要
n× m非负实数矩阵的每列元素之和的几何平均值不小于其每行元素的几何平均值之和 ,运用它给出了一类和 (或积 )式不等式的简捷证明 ,也导出了著名不等式 :Cauchy不等式。
In this paper,by appliying the property that the geometric average of the sum of elements of the column of a n×m real matrix is non-lower than the sum of the geometric average of elements of the row,the simple and direct proof of the class of inequalities on sum or product is agined,for celebrated Cauchy-inequality and Holder-inequality,their extend form are derived.
