内部扩散限制聚集(IDLA)是图G$上的一个随机增长模型,它描述了从G$的原点(某个固定顶点)开始随机增长的顶点集的形成。粒子从原点开始,执行简单的随机行走;每个粒子移动,直到它降落在一个之前没有被其他粒子访问过的位置。在$G$中被占用的站点的随机集合被称为IDLA簇。 在本文中,我们认为IDLA Sierpinski垫片图,并表明,IDLA集群填充球(在图度量)的概率为1。
Internal diffusion-limited aggregation (IDLA) is a stochastic growth model on a graph $G$ which describes the formation of a random set of vertices growing from the origin (some fixed vertex) of $G$. Particles start at the origin and perform simple random walks; each particle moves until it lands on a site which was not previously visited by other particles. This random set of occupied sites in $G$ is called the IDLA cluster. In this paper we consider IDLA on Sierpinski gasket graphs, and show that the IDLA cluster fills balls (in the graph metric) with probability 1.
