... integers, and even if it is, the size of the set is the same as the size of the original set (as opposed to what happens with the measure of a set of real numbers). Acknowledgement: The authors ... fact it is not hard to show that W is a maximal k-sum-free set (i.e. it is not a proper subset of any k-sum free subset of (0, 1]). The parameter c controls the...

... loops are con- sidered. Note that the iterated line graph of a path eventually becomes the empty graph and that the iterated line graphs of cycles and K 1,3 (whose line graph is a tri- angle) ... the maximum and minimum degree both have order Θ(2 k ). Niepel, et al., have conjectured that the maximum degrees of all iterated line graphs, with the exception of...

... one-factor) of G is a subgraph of G in which each vertex has degree at most one. A basic question in combinatorial optimization is, “What is the size of a maximum matching in a given graph?” ... graph G is an expander. Namely, for any integers d ≥ 3 and g and a graph G satisfying n(d, g) < 2n 0 (d, g), the second largest eigenvalue of the adjacency matrix λ(G)...
