考虑一个在3,2-交替树上随机游动的增长系统,其中节点的世代在有两个和三个孩子之间交替。任何时候,一个粒子落在一个以前没有被访问过的节点上,一个新的粒子就会在这个节点上被激活,并开始它自己的随机行走。所描述的模型属于被统称为青蛙模型的一类问题。建立在最近的递归证明(这意味着无限多的青蛙击中根的概率为1)的正规二叉树,本文建立递归的3,2-交替的情况下。
Consider a growing system of random walks on the 3,2-alternating tree, where generations of nodes alternate between having two and three children. Any time a particle lands on a node which has not been visited previously, a new particle is activated at that node, and begins its own random walk. The model described belongs to a class of problems that are collectively referred to as the frog model. Building on a recent proof of recurrence (meaning infinitely many frogs hit the root with probability one) on the regular binary tree, this paper establishes recurrence for the 3,2-alternating case.
