关于自由积图的距离-k图的谱分布

On the spectral distributions of distance-k graph of free product graphs

Octavio Arizmendi, Tulio Gaxiola

摘要:

我们计算了$d$ -正则树的距离- $k$图关于真空态的分布。从这个结果中,我们证明了$d$ -正则图的距离- $k$图收敛于正则树的距离- $k$图的分布。最后,我们证明了当$d$趋于无穷大时,$d$ -折叠自由积图的距离- $k$图的渐近分布是由$P_k(s)$的分布给出的,其中$s$是一个循环随机变量,$P_k$是$k$ -th Chebychev多项式.

英文摘要:

We calculate the distribution with respect to the vacuum state of the distance-$k$ graph of a $d$-regular tree. From this result we show that the distance-$k$ graph of a $d$-regular graphs converges to the distribution of the distance-$k$ graph of a regular tree. Finally, we prove that, properly normalized, the asymptotic distributions of distance-$k$ graphs of the $d$-fold free product graph, as $d$ tends to infinity, is given by the distribution of $P_k(s)$, where $s$ is a semicircle random variable and $P_k$ is the $k$-th Chebychev polynomial.
