考虑边赋权图,其权是阶数相同的方阵.加权图的邻接矩阵和定向加权图的斜邻接矩阵以自然的方式定义.给出了具有唯一完美匹配的二部图的赋权图的邻接矩阵和斜邻接矩阵的逆矩阵的表达式,并说明这些公式在分块矩阵求逆中的应用.
The weighted graphs that the edge weights are square matrices with fixed orders are considered.The adjacency and skew-adjacency matrix of a weighted graph is defined in a natural way.The formula is obtained for the inverses of the adjacency and skew-adjacency matrices of a weighted graph when its underlying graph is a bipartite graph with a unique perfect matching,and some applications are given in inverse of block matrices.
