摘要 标量值解析函数的最大模原理在多大程度上对矩阵值解析函数有效?作为回应,我们讨论了此类函数的一些最大范数原理,这些函数似乎并不广为人知,推导出其奇异值的最大和最小原理,并对解析剂和矩阵指数进行了一些观察。
Abstract To what extent is the maximum modulus principle for scalar-valued analytic functions valid for matrix-valued analytic functions? In response, we discuss some maximum norm principles for such functions that do not appear to be widely known, deduce maximum and minimum principles for their singular values, and make some observations concerning resolvents and matrix exponentials.
