自相互作用扩散IV:收敛速率

Self-interacting diffusions IV: Rate of convergence

Michel Benaim, Olivier Raimond

摘要:

自相互作用扩散是生活在由随机微分方程定义的紧致黎曼流形上的过程,其中漂移项取决于该过程的过去经验测量。这个测度的渐近性是由一个确定性的动力系统决定的,并且在一定的条件下,它几乎必然收敛于一个确定性测度(参见Benaïm,Ledoux,Raimond(2002)and Benaïm,Raimond(2005))。我们在这里感兴趣的是这种收敛的速度。证明了一个中心极限定理。特别是,这表明,更大的相互作用排斥更快的是收敛。

英文摘要:

Self-interacting diffusions are processes living on a compact Riemannian manifold defined by a stochastic differential equation with a drift term depending on the past empirical measure of the process. The asymptotics of this measure is governed by a deterministic dynamical system and under certain conditions it converges almost surely towards a deterministic measure (see Benaïm, Ledoux, Raimond (2002) and Benaïm, Raimond (2005)). We are interested here in the rate of this convergence. A central limit theorem is proved. In particular, this shows that greater is the interaction repelling faster is the convergence.
