非负矩阵的高秩数值域

The higher rank numerical range of nonnegative matrices

Aikaterini Aretaki, John Maroulas

摘要:

本文研究了著名的Perron-Frobenius理论,涉及到不可约的按项非负矩阵$A$的高阶数值域$Λ_{k}(A)$,并推广了$Λ_{k}(A)$中最大模元素的概念。此外,该理论的应用程序的$Λ_{k}(L(λ))$的Perron多项式$L(λ)$阐述通过其友矩阵$C_{L}$。

英文摘要:

In this article the well known "Perron-Frobenius theory" is investigated involving the higher rank numerical range $Λ_{k}(A)$ of an irreducible and entrywise nonnegative matrix $A$ and extending the notion of elements of maximum modulus in $Λ_{k}(A)$. Further, an application of this theory to the $Λ_{k}(L(λ))$ of a Perron polynomial $L(λ)$ is elaborated via its companion matrix $C_{L}$.
