论文摘要
给定两个$ d \ times d $矩阵,例如$ a $和$ b $,何时$ p(a)$和$ p(b)$对每个多项式$ p $具有相同的``size''?在本文中,当使用的大小是光谱规范时,我们在$ d = 2 $和$ d = 3 $的情况下提供明确的结果。
Given two $d\times d$ matrices, say $A$ and $B$, when do $p(A)$ and $p(B)$ have the same ``size'' for every polynomial $p$? In this article, we provide definitive results in the cases $d=2$ and $d=3$ when the notion of size used is the spectral norm.
