    Classes of general H-matrices 
    Bru, R.; Corral Ortega, Cristina; Gimenez Manglano, María Isabel; Mas Marí, José (Elsevier, 2008)
    [EN] Let M(A) denote the comparison matrix of a square H-matrix A, that is, M(A) is an M-matrix. H-matrices such that their comparison matrices are non-singular are well studied in the literature. In this paper, we study ...

    Schur complement of general H-matrices 
    Bru García, Rafael; Corral Ortega, Cristina; Gimenez Manglano, María Isabel; Mas Marí, José (John Wiley & Sons, 2009)
    [EN] It is well known that the Schur complement of some H-matrices is an H-matrix. In this paper, the Schur complement of any general H-matrix is studied. In particular, it is proved that the Schur complement, if it exists, ...
