A Survey of M-Matrix Characterizations. I. Nonsingular M-Matrices.
Abstract
The purpose of this survey is to classify systematically a widely ranging list of characterizations of nonsingular M-matrices from the economics and mathematics literatures. These characterizations are grouped together in terms of their relationships to the properties of (1) positivity of principal minors (2) inverse-positivity and splittings (3) stability and (4) semi-positivity and diagonal dominance. A list of forty eqivalent conditions is given for a square matrix A with nonpositive off-diagonal entries to be a nonsingular M-matrix. These conditions are grouped into classes in order to identify those that are equivalent for arbitrary real matrices A. In addition, other remarks relating nonsingular M-matrices to certain complex matrices are made and the recent literature on these general topics is surveyed. (Author)
