... an unextendible sequence S in G. 2 On Unextendible Sequences We begin by describing u(G) for cyclic group C n and for any finite abelian group. For some real number x ∈ R, let x = min{m ∈ Z|m ≥ x}. Lemma ... modulo n, Canad. Math. Bull., 18(1975), 27-29. [2] W. D. Gao and A.

... right hand sides contains at most one point, and the third set contains at most four points. Since |N 2 (a)| = 10, the second set must contain at least five points. However, since N 2 (a) ∩ N 2 (b)andN 2 (a) ... points in each set must be arranged according to the same unique pattern: a pentagon where the sides have length 1 and any other distance is 2. Now, pick one of the two remaining poi...

... Theorem 1.2 and it serves as an introduction to it. We begin with a lemma about selecting induced forests of a particular kind in a bipartite graph. We introduce some terminology. Let H be a bipartite ... ··· ∪ M  induces a forest in G. We let T be the component of this forest containing the single vertex of M  . Since every vertex of M i−1 ,  < i ≤ k, has at least one neighbor in...
