On a criterion for the nonsingularity of complex matrices
Authors:
- Tomasz Szulc
Abstract
A new criterion for the nonsingularity of an n×n complex matrix is presented. Based on the criterion, new regions of localization of the eigenvalues of an arbitrary square matrix A, as well as new sufficient conditions for a square matrix to have all its eigenvalues with positive real parts, are obtained. In consequence, an inequality which is satisfied by each eigenvalue of A and a new criterion for a real square matrix to be an M-matrix are also derived. © 1992.
