o:28912 A note on the Laplacian resolvent energy, Kirchhoff index and their relations en 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). Keywords: Graph energy; Laplacian resolvent energy; Kirchhoff index 1552101 2664-2557 2023-04-24T10:09:50.463Z 44 no 46 Emir Zogić Državni univerzitet u Novom Pazaru 0000-0002-1355-3785 Eldin Glogić Državni univerzitet u Novom Pazaru person 0000-0001-6295-8298 application/pdf 355682 https://phaidrabg.bg.ac.rs/o:28912 no yes 1 70 92000001 20A01 Discrete Mathematics Letters 2 32 37 2019
