Abstract
For (weighted) graphs several labeling properties and their relation to the eigenvalues of the Laplacian matrix of a graph are considered. Several upper and lower bounds on the bandwidth and other minβsum problems are derived. Most of these bounds depend on Laplace eigenvalues of the graphs. The results are applied in the study of bandwidth and the minβsums of random graphs, random regular graphs, and Kneser graphs. Β© John Wiley & Sons, Inc.

An edge-labeling f of a graph G is an injection from E(G) to the set of integers. The edge-bandwidth of G is B H (G) min f {B H (f )}, where B H (f ) is the maximum difference between labels of incident edges of G. The theta graph Γ(l 1 , F F F ,l m ) is the graph consisting of m pairwise internally
Using multiplicities of eigenvalues of elliptic self-adjoint differential operators on graphs and transversality, we construct some new invariants of graphs which are related to tree-width.
