Abstract

We prove a Frobenius norm inequality for three matrices, analogous to the well-known Bottcher--Wenzel inequality. The situation is also similar: standard inequalities would yield an upper bound, which however can be reduced by means of further, detailed investigations.

三个矩阵的范数不等式

我们证明了三个矩阵的Frobenius范数不等式，类似于著名的botcher—Wenzel不等式。情况也是类似的:标准不等式会产生一个上界，但是可以通过进一步详细的调查来缩小它。
