- W2019643208 abstract "An n × n matrix is called an N -matrix if all principal minors are negative. In this paper, we are interested in N -matrix completion problems, that is, when a partial N -matrix has an N -matrix completion. In general, a combinatorially or non-combinatorially symmetric partial N -matrix does not have an N -matrix completion. Here we prove that a combinatorially symmetric partial N -matrix has an N -matrix completion if the graph of its specified entries is a 1-chordal graph. We also prove that there exists an N -matrix completion for a partial N -matrix whose associated graph is an undirected cycle." @default.
