Block H-matrices and spectrum of block matrices

Applied Mathematics and Mechanics, 2002
Several generalizations for block \(H\)-matrices are studied by the concept of \(G\)-functions. Equivalent characterizations of \(H\)-matrices are discussed. A spectrum location of block \(H\)-matrices is determined.

Decomposing Matrices into Blocks

SIAM Journal on Optimization, 1998
Summary: In this paper we investigate whether matrices arising from linear or integer programming problems can be decomposed into so-called bordered block diagonal form. More precisely, given some matrix \(A\), we try to assign as many rows as possible to some number \(\beta\) of blocks of size \(\kappa\) such that no two rows assigned to different ...

Block P-matrices

Linear and Multilinear Algebra, 1998
Several possibilities to generalize P-matrices to block form are discussed. Unfortunately certain equivalences holding for P-matrices do not carry over to the block case. We opt for one such generalization calling it block P-matrices. It has the most analogies to the usual P-matrices.

Matrices Doubly Stochastic by Blocks

Canadian Journal of Mathematics, 1977
The present work stems from the following classical result, due to G. H. Hardy, J. E. Littlewood, G. Pólya [7], and R. Rado [10].THEOREM 1. Concerning a pair of n-tuples x, y ϵ Rn, the following four statementsare equivalent:(a) for every continuous, convex function f : R ...
