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. Bibliography: 8 titles. [ABSTRACT FROM AUTHOR]
