SummaryA一般比较参数的期望某些多时间泛函的无限系统的线性相互作用的扩散不同的扩散系数。作为一个应用,我们证明了聚类发生的情况下,对称化的相互作用内核是经常性的,和组件的值在一个区间上有界的一侧。该技术还提供了一个替代的证明,在紧凑的间隔的情况下,聚类。
SummaryA general comparison argument for expectations of certain multitime functionals of infinite systems of linearly interacting diffusions differing in the diffusion coefficient is derived. As an application we prove clustering occurs in the case when the symmetrized interaction kernel is recurrent, and the components take values in an interval bounded on one side. The technique also gives an alternative proof of clustering in the case of compact intervals.
