3-方体的一个性质
A property of 3-cube
【摘要】 在相关文献中,引入了α-子图的概念来探索超欧拉图的极大欧拉生成子图的边数,并且证明了2-方体在加入一条新边的情况下是一个3/5-子图.研究了3-方体,证明了3-方体在加入一条新边的情况下是一个(9/13)-子图.
【Abstract】 In some references,the author has introduced a new concept of α-subgraph to explore the number of edges of its maximum spanning eulerian subgraph of a supereulerian graph.The author also proved a 2-cube added with a new edge is a3/5-subgraph.In this paper,3-cube has been studied and a property of it that 3-cube added with a new edge is a (9/13)-subgraph has been found.
