Quasi-block-stochastic matrices
Werner Kuich · Pacific Journal of Mathematics · 1968
The quasi-block-stochastic matrices are introduced as a generalization of the block-stochastic and the quasi-stochastic matrices.The derivation of theorems is possible which are similar to those derived for block-stochastic matrices by W. Kuich and K. Walk and for quasi-stochastic matrices by Haynsworth.Among other theorems the theorem on the group property, the reduction formula and its application to nonnegative matrices holds in a modified manner.An example illustrates the definitions and theorems.
