## Abstract We show that for an interval graph given in the form of a family of intervals, a maximum independent set, a minimum covering by disjoint completely connected sets or cliques, and a maximum clique can all be found in __O__(__n__ log __n__) time [__O__(__n__) time if the endpoints of the

We give a lower bound for the treewidth of a graph in terms of the second smallest eigenvalue of its Laplacian matrix. We use this lower bound to show that the treewidth of a d-dimensional hypercube is at least 3 We generalize this result to Hamming graphs. We also observe that every graph G on n v
