Subgraphs Matching Number and Signless Laplacian Spectra of Graphs
摘要
Abstract
Let G be a graph and H be a subgraph of G.A set of pairwise independent subgraphs G that are all isomorphic to copies of H is called an H-matching of G.The maximum cardinality of an H-matching is called the H-matching number of G and is denoted by v(H,G).In this paper we investigate some relations between v(H,G) and signless Laplacian spectrum of G.By a similar discussion we also get some relations between v(H,G) and Laplacian spectrum of G.关键词
