生成无限随机图

Generating infinite random graphs

Csaba Biró, Udayan B. Darji

摘要:

我们定义了一个随机图的增长模型。给定一个非负整数序列$\{d_n\}_{n=0}^\infty$,其性质为$d_i\leq i$,我们通过以下过程构造了一个关于可数无穷多个顶点$v_0,v_1\ldots$的随机图:顶点$v_i$连接到$\{v_0,\ldots,v_{i-1}\}$的随机选择的基数为$d_i$的子集.我们研究由此产生的概率空间。特别地,我们给出了随机图的一个新的刻画,并给出了构造无限随机树的概率方法。

英文摘要:

We define a growing model of random graphs. Given a sequence of nonnegative integers $\{d_n\}_{n=0}^\infty$ with the property that $d_i\leq i$, we construct a random graph on countably infinitely many vertices $v_0,v_1\ldots$ by the following process: vertex $v_i$ is connected to a subset of $\{v_0,\ldots,v_{i-1}\}$ of cardinality $d_i$ chosen uniformly at random. We study the resulting probability space. In particular, we give a new characterization of random graph and we also give probabilistic methods for constructing infinite random trees.
