Abstract
En 中文
It is shown by a counterexample that an eigenvalue localization set for matrices involved with a positive integer k, as one of the main theorems provided by Cvetkovic et al. (2015), does not hold in general for the case that k is odd. And then a new eigenvalue localization set for matrices which is a correction of this set is given. (C) 2017 Elsevier Inc.
