格点II上的稳态聚结行走:熵

Stationary coalescing walks on the lattice II: Entropy

Jon Chaika, Arjun Krishnan

摘要:

本文是Chaika和Krishnan [arXiv:1612.00434]的续篇。我们再次考虑整数格Z^d上最近邻半无限游动族上的平移不变测度。我们假设一旦行走相遇,它们就合并。我们考虑这些系统的各种熵性质。我们表明,在完全正熵的系统中,双无限轨道必须携带熵。在二维定向行走的情况下,我们表明,正熵保证所有的轨迹不能是双无限的。为了证明我们的定理是正确的,我们构造了一个平稳的离散时间对称排它过程,它的粒子轨道形成携带熵的双无限轨道。

英文摘要:

This paper is a sequel to Chaika and Krishnan [arXiv:1612.00434]. We again consider translation invariant measures on families of nearest-neighbor semi-infinite walks on the integer lattice Z^d. We assume that once walks meet, they coalesce. We consider various entropic properties of these systems. We show that in systems with completely positive entropy, bi-infinite trajectories must carry entropy. In the case of directed walks in dimension 2 we show that positive entropy guarantees that all trajectories cannot be bi-infinite. To show that our theorems are proper, we construct a stationary discrete-time symmetric exclusion process whose particle trajectories form bi-infinite trajectories carrying entropy.
