Nai Hua. Ji · Gongcheng shuxue xuebao · 2005
By using the graph-theoretic method, the completion problems for a partial inverse Mmatrix with any order are discussed when its corresponding graph of the partial inverse M-matrix is a 2-chordal graph. We also present completion theorem of 2-chordal graphs and give the corresponding algorithm.
