Opis (eng)

Abstract: Let G be a simple graph of order n and let L be its Laplacian matrix. Eigenvalues of the matrix L are denoted by μ1, μ2, • • • , μn and it is assumed that μ1 > μ2 > • • • > μn. The Laplacian resolvent energy and Kirchhoff index of the graph G are defined as RL(G)=∑▒〖1/(n+1-μi)〗 and Kf(G)=n∑_(i=1)^(n-1)▒〖1/μi〗, respectively. In this paper, we derive some bounds on the invariant RL(G) and establish a relation between RL(G) and Kf (G).
