AI总结:

研究在\(n\geq5\)的\(n\)维对偶立方体\(F_n\)中构建两棵完全独立生成树的问题,利用\(F_n\)簇超立方体结构扩展构造方法,并提出递归算法减小树直径,还对\(k\)棵树的存在性提出猜想。

AI中文摘要:

本文证明了对于每个\(n\geq5\),在\(n\)维对偶立方体\(F_n\)(超立方体的一种变体)中存在两棵完全独立的生成树。为此,利用\(F_n\)簇的超立方体结构将完全独立生成树(CIST)的构造从\((n - 1)\)维超立方体扩展到对偶立方体。还提出一种递归算法来构建这两棵树并减小其直径。最后,提出了关于对偶立方体中\(k\)棵完全独立生成树存在性的猜想。

英文摘要:

In this paper, we prove the existence of two completely independent spanning trees in the $n$-dimensional dual-cube $F_n$, a variant of the hypercube, for every $n \geq 5$. To this end, we use the hypercube structure of the clusters of $F_n$ to extend the construction of CIST from the $(n-1)$-dimensional hypercube to the dual-cube. In addition, we provide a recursive algorithm that builds the two trees while improving their diameters. Finally, we propose a conjecture regarding the existence of $k$ completely independent spanning trees in the dual-cube.
