Diagonal dominance characterization of $PM$- and $PH$-matrices
L. Yu. Kolotilina St. Petersburg Department of V. A. Steklov Institute of Mathematics, Russian Academy of Sciences, St. Petersburg, Russia
Abstract:
New characterizations of the so-called $PM$- and $PH$-matrices in terms of generalized diagonal dominance are obtained and used to derive some of their properties. Also it is proved that a $PH$-matrix necessarily has a certain number of strictly diagonally dominant rows. Bibl. – 8 titles.
Key words and phrases:
$PM$-matrix, $PH$-mdtrix, quasi-$PM$-matrix, quasi-$PH$-matrix, aggregated matrices, generalized diagonal dominance, $\mathcal S$-strict diagonal dominance.
