论文摘要
给定图的无标志性的拉普拉斯Q和无符号的边缘拉普拉斯可能是可逆的。研究了Q和S的Moore-Penrose对逆。特别是，使用发射矩阵，我们发现了摩尔·彭罗斯（Moore-Penrose）的Q和s的组合公式。另外，我们提出了Q和S的iNversial公式的组合公式，以用于奇数独线图。
The signless Laplacian Q and signless edge-Laplacian S of a given graph may or may not be invertible. The Moore-Penrose inverses of Q and S are studied. In particular, using the incidence matrix, we find combinatorial formulas of the Moore- Penrose inverses of Q and S for trees. Also we present combinatorial formulas of the inverses of Q and S for odd unicyclic graphs.
