Two results on the signless Laplacian matrix of a graph
-
摘要: 设G是具有n个顶点和m条边的简单无向图,Q(G)是图G的无符号拉普拉斯矩阵.讨论了Q(G)的谱半径和与谱半径对应的特征向量的分量.Abstract: Let G be a simple connected graph with n vertices and m edges and Q(G) its signless Laplacian matrix. The spectral radius and the entries of the principal vector of Q(G) were investigated.
