Spectral Condition for a Graph to be Hamiltonian with respect to Normalized Laplacian

Combinatorics 2012-07-31 v1

Abstract

Let G be a graph and let \Delta,\delta be the maximum and minimum degrees of G respectively, where \Delta/\delta<c<\sqrt{2} and c is a constant. In this paper we establish a sufficient spectral condition for the graph G to be Hamiltonian, that is, the nontrivial eigenvalues of the normalized Laplacian of G are sufficiently close to 1.
