Abstract

Abstract : 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 completion of a partial N 0 -matrix whose associated graph is a directed cycle.
