Title: | On the inertia of the block H-matrices | Authors: | Kostić Vladimir Cvetković Ljiljana |
Issue Date: | 2017 | Journal: | Numerical Linear Algebra with Applications | Abstract: | Copyright © 2017 John Wiley & Sons, Ltd. The problem of determining matrix inertia is very important in many applications, for example, in stability analysis of dynamical systems. In the (point-wise) H-matrix case, it was proven that the diagonal entries solely reveal this information. This paper generalises these results to the block H-matrix cases for 1, 2, and ∞ matrix norms. The usefulness of the block approach is illustrated on 3 relevant numerical examples, arising in engineering. | URI: | https://open.uns.ac.rs/handle/123456789/17889 | ISSN: | 1070-5325 | DOI: | 10.1002/nla.2101 |
