چکیده
|
Let g be a simple connected graph with n ≤ 2 vertices and m edges, and let μ1 ≥ μ2 ≥...≥μn1 >μn=0 be its laplacian eigenvalues. the kirchhoff index and laplacianenergylike invariant (lel) of graph g are defined as kf(g)=nσi=1n11/μi and lel(g)=σi=1n1 √μi, respectively. in this paper we consider relationship between kf(g) and lel(g).
