The Laplacian spectral radius of graphs
✍ Liang Lin πŸ“‚ Article πŸ“… 2008 πŸ› Elsevier Science 🌐 English βš– 89 KB

Let G be an n-vertex (n 3) simple graph embeddable on a surface of Euler genus Ξ³ (the number of crosscaps plus twice the number of handles). Denote by the maximum degree of G. In this paper, we first present two upper bounds on the Laplacian spectral radius of G as follows: (i) (ii) If G is 4-conn

In this paper, we investigate how the Laplacian spectral radius changes when one graph is transferred to another graph obtained from the original graph by adding some edges, or subdivision, or removing some edges from one vertex to another.
