Abstract

For the Abelian sandpile model on Sierpiński graphs, we investigate several statistics such as average height, height probabilities and looping constant. In particular, we calculate the expected average height of a recurrent sandpile on the finite iterations of the Sierpiński gasket and we also give an algorithmic approach for calculating the height probabilities of recurrent sandpiles under stationarity by using the connection between recurrent configurations of the Abelian sandpile Markov chain and uniform spanning trees. We also calculate the expected fraction of vertices of height i for i { 0 , 1 , 2 , 3 } of sandpiles under stationarity and relate the bulk average height to the looping constant on the Sierpiński gasket.

阿贝尔沙堆的平均高度和Sierpiński图上的循环常数。
对于Sierpiński图上的阿贝尔沙堆模型,研究了平均高度、高度概率和循环常数等统计量。特别地,我们在Sierpiński垫片的有限迭代上计算了循环沙堆的期望平均高度,并利用阿贝尔沙堆马尔可夫链的循环构型与一致生成树之间的联系,给出了一种计算平稳下循环沙堆高度概率的算法方法。我们还计算了平稳性条件下i∈{0,1,2,3}的沙堆高度为i的顶点的期望分数,并将总体平均高度与Sierpiński垫片上的循环常数联系起来。
