The minus partial order and the shorted matrix. (English) Zbl 0605.15004
Several new properties of the star and minus partial order are established. Also the generalized inverses are shown which characterize the shorted matrix. For the minus order used definitions and conditions are given. Several theorems are proved which govern the existence of the infinum and the supremum of a pair of matrices of the same order.
