Characterization of the Existence of an N (0)-Completion of a Partial N (0)-Matrix with an Associated Directed Cycle
An n × n matrix is called an N (0)-matrix if all its specified principal minors are nonpositive. In the context of partial matrices, a partial matrix is called a partial N (0)-matrix if all its specified principal minors are nonpositive. In this paper we characterize the existence of an N (0)-matrix...
