著名的1-2-3猜想断言至少有三个顶点的连通图的边可以用1、2和3赋权,使得相邻的顶点得到不同的权重和。在这篇文章中,我们证明了这个猜想对Halin图成立。此外,这一界限很紧。
The well-known 1-2-3 Conjecture asserts the edges of every connected graph with at least three vertices can be weighted with 1, 2 and 3 so that adjacent vertices receive distinct sums of weights. In this paper, we show this conjecture holds for Halin graph. Moreover, this bound is tight.
