具有指定谱的置换非负矩阵
Permutative nonnegative matrices with prescribed spectrum
摘要:
n × n置换矩阵是其中每一行都是第一行的置换的矩阵。本文将Paparella在[Electron. J.线性代数31(2016)306-312]中给出的结果推广到更一般的实数和复数的列表,并对他提出的一个问题给出了否定的回答.
英文摘要:
An n x n permutative matrix is a matrix in which every row is a permutation of the first row. In this paper the result given by Paparella in [Electron. J. Linear Algebra 31 (2016) 306-312] is extended to a more general lists of real and complex numbers, and a negative answer to a question posed by him is given.
