Balls into Bins模型的混沌传播

Propagation of Chaos for a Balls into Bins Model

Nicoletta Cancrini, Gustavo Posta

摘要:

考虑最初放置在$L$箱中的有限数量的球。在每个时间步骤,从每个非空的箱子中取出一个球。然后所有的球被统一重新分配到箱子里。这个有限的马尔可夫链被称为重复的Balls-into-Bins过程,是一个具有并行更新的离散时间相互作用粒子系统。我们证明,从一个合适的(混沌)的初态,作为$L\to+\infty$,在每个箱中的球的数量变得独立于其余的系统,即我们有混沌的传播。我们进一步研究了极限非线性过程的一些平衡性质。

英文摘要:

Consider a finite number of balls initially placed in $L$ bins. At each time step a ball is taken from each non-empty bin. Then all the balls are uniformly reassigned into bins. This finite Markov chain is called Repeated Balls-into-Bins process and is a discrete time interacting particle system with parallel updating. We prove that, starting from a suitable (chaotic) set of initial states, as $L\to+\infty$, the numbers of balls in each bin becomes independent from the rest of the system i.e. we have propagation of chaos. We furthermore study some equilibrium properties of the limiting nonlinear process.
