Abstract: The paper introduces new subclasses, called Pℋ$$ \mathrm{\mathscr{H}} $$N(π) and Pℋ$$ \mathrm{\mathscr{H}} $$QN(π), of (nonsingular) ℋ$$ \mathrm{\mathscr{H}} $$-matrices of order n dependent on a partition π of the index set {1, . . ., n},… read more here.

Abstract: The paper considers some classes of block matrices that can be regarded as block generalizations of the class of ℋ$$ \mathrm{\mathscr{H}} $$-matrices and interrelations among them. New bounds for the infinity norm of inverses for… read more here.
