Characterization of the Existence of an N0-Completion of a Partial N0-Matrix with an Associated Directed Cycle
An n×n matrix is called an N0-matrix if all its specified principal minors are nonpositive. In the context of partial matrices, a partial matrix is called a partial N0-matrix if all its specified principal minors are nonpositive. In this paper we characterize the existence of an N0-matrix completion...
