### Propagation of chaos for a balls into bins model

Nicoletta Cancrini and Gustavo Posta

#### Abstract

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 become 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*.
