具有无限程相互作用的相互作用粒子系统的再生

Regeneration for interacting particle systems with interactions of infinite range

Eva Loecherbach

摘要:

考虑了高噪声条件下$\Z^d$上具有有限状态空间和无限范围相互作用的相互作用粒子系统。假设的变化率是连续的,一个Dobrushin样的条件成立,我们表明,该过程是经常性的哈里斯的意义上,并构造明确的再生时间的过程中限制有限的圆柱集。我们表明,再生期的长度承认指数时刻。再生时间几乎必然是有限的证明依赖于广义纸牌屋链的耦合构造。

英文摘要:

We consider an interacting particle system on $\Z^d$ with finite state space and interactions of infinite range in a high-noise regime. Assuming that the rate of change is continuous and that a Dobrushin-like condition holds, we show that the process is recurrent in the sense of Harris and construct explicit regeneration times for the process in restriction to finite cylinder sets. We show that the length of a regeneration period admits exponential moments. The proof that regeneration times are almost surely finite relies on a coupled construction of generalized house-of-cards chains.
