我们将哈密尔顿可系带图 G 定义为超哈密尔顿可系带图(超 HL),如果满足以下任一条件: 特别是超立方体 Qnis 超 HL。如果图 G 具有毛虫生成树,则该图 G 是毛虫可生成的(CS)。我们提出了几个关于 CS 图乘积的定理。结果表明,两个 CS 图的乘积(其中至少一个的最大度数为 3)就是 CS。
We define a Hamilton laceable graph G to be hyper-Hamilton laceable (hyper HL) if either In particular, the hypercube Qnis hyper HL. A graph G is caterpillar-spannable (CS) if it has a spanning tree which is a caterpillar. We present several theorems concerning products of CS graphs. It is shown that the product of two CS graphs such that at least one of them has maximum degree 3 is CS.
