(2,3,c)-循环有向图中的哈密顿圈

Hamiltonian cycles in (2,3,c)-circulant digraphs

Dave Witte Morris, Joy Morris, Kerri Webb

摘要:

设D是连通集为{2,3,c}的n阶循环有向图.(假设D是无环的,且出度为3。)S.C.Locke和D.Witte的工作暗示,如果n是6的倍数,c是(n/2)+ 2或(n/2)+ 3,且c是偶数,则D没有哈密顿圈。对于所有其他情形,我们在D中构造了一个哈密顿圈.

英文摘要:

Let D be the circulant digraph with n vertices and connection set {2,3,c}. (Assume D is loopless and has outdegree 3.) Work of S.C.Locke and D.Witte implies that if n is a multiple of 6, c is either (n/2) + 2 or (n/2) + 3, and c is even, then D does not have a hamiltonian cycle. For all other cases, we construct a hamiltonian cycle in D.
