Gufang Mou, Ting‐Zhu Huang · Advances in Mathematics · 2010
In this paper, based on the completion problem of partial P -matrix for 1- chordal graph, we obtain the partial positive P -matrix completions of k-chordal graphs and k-chordal block graphs under some conditions and solve partial positive P -matrix completion problems with zeros in the inverse completion for k-chordal graphs and k-chordal block graphs (k � 2).
