An n Γ n matrix is called an N -matrix if all its principal minors are negative. In this paper, we are interested in the symmetric N -matrix completion problem, that is, when a partial symmetric N -matrix has a symmetric N -matrix completion. Here, we prove that a partial symmetric N -matrix has a s
Necessary and sufficient conditions are given on the data for completability of a partial symmetric inverse M-matrix, the graph of whose specified entries is a cycle, and these conditions coincide with those we identify to be necessary in the general (nonsymmetric) case. Graphs for which all partial
