随机几何图的距离-l色数

The Distant-l Chromatic Number of Random Geometric Graphs

Yilun Shang

摘要:

随机几何图$G_n$是通过在公共有界概率分布下独立地选取$\mathbb{R}^d$中的$n$顶点而得到的,其中两个顶点相邻当且仅当它们的$l^p$ -距离至多为$r_n$ .我们研究了$l\ge1$的$G_n$的远- $l$色数$χ_l(G_n)$.在几乎处处收敛的意义下,给出了$χ_l(G_n)$与色数$χ(G_n)$之比的完整图象.

英文摘要:

A random geometric graph $G_n$ is given by picking $n$ vertices in $\mathbb{R}^d$ independently under a common bounded probability distribution, with two vertices adjacent if and only if their $l^p$-distance is at most $r_n$. We investigate the distant-$l$ chromatic number $χ_l(G_n)$ of $G_n$ for $l\ge1$. Complete picture of the ratios of $χ_l(G_n)$ to the chromatic number $χ(G_n)$ are given in the sense of almost sure convergence.
