Keywords: | Sign regular matrices Total nonpositivity |
Issue Date: | 1-Jun-2010 | Citation: | Huang, R., Chu, D. (2010-06-01). Total nonpositivity of nonsingular matrices. Linear Algebra and Its Applications 432 (11) : 2931-2941. ScholarBank@NUS Repository. https://doi.org/10.1016/j.laa.2009.12.043 | Abstract: | In this paper, nonsingular totally nonpositive matrices are studied and new characterizations are provided in terms of the signs of minors with consecutive initial rows or consecutive initial columns. These characterizations extend an existing characterization that uses some restrictive hypotheses. © 2010 Elsevier Inc.
