Abstract
Let G be a connected graph of order n with Laplacian eigenvalues mu(1)(G) >= mu(2)(G) >= ... >= mu(n)(G) = 0. The Laplacian-energy-like invariant of G, is defined as LEL(G) =Sigma(n-1)(l=1) root mu(i) In this paper, we investigate the asymptotic behavior of the 3.6.24 lattice in terms of Laplacian-energy-like invariant as m, n approach infinity. Additionally, we derive that M-t (n, m), M-c (n, m) and M-f (n, m) have the same asymptotic Laplacian-energy-like invariants.
