Abstract

We investigate three types of Internal Diffusion Limited Aggregation (IDLA) models. These models are based on simple random walks on (cid:90) 2 with inﬁnitely many sources that are the points of the vertical axis I ( ∞ ) = {0} × (cid:90) . Various properties are provided, such as stationarity, mixing, stabilization and shape theorems. Our results allow us to deﬁne a new directed (w.r.t.the horizontal direction) random forest spanning (cid:90) 2 , based on an IDLA protocol, which is invariant in distribution w.r.t.vertical translations.

双向定向IDLA森林

我们研究了三种类型的内部扩散有限聚集(IDLA)模型。这些模型基于(cid:90) 2上的简单随机漫步，具有无限多个源，这些源是垂直轴I(∞)= {0}× (cid:90)的点。提供了各种性质，如平稳性、混合性、稳定性和形状定理。我们的结果允许我们基于IDLA协议定义一个新的有向(水平方向)随机森林(cid:90) 2，该协议在垂直方向上的分布是不变的。
