末道渗流模型中的Busemann函数和平衡测度

Busemann functions and Equilibrium measures in last passage percolation models

Eric Cator, Leandro P. R. Pimentel

摘要:

二维渗流增长模型和一维粒子过程之间的相互作用已经成为有趣的数学现象的富有成效的来源。在本文中,我们开发的Hammersley最后一次通过渗流模型与独立同分布的Busemann函数的构造之间的连接。随机权,以及相关的(多类)相互作用流体系统的平衡(或时不变)测度的存在性、遍历性和唯一性.正如我们将看到的,在经典的哈默斯利模型中,每个点的权重为1,这种方法带来了一个新的,而最长的增加子序列问题的几何解决方案,以及一个中心极限定理的Busemann函数。

英文摘要:

The interplay between two-dimensional percolation growth models and one-dimensional particle processes has been a fruitful source of interesting mathematical phenomena. In this paper we develop a connection between the construction of Busemann functions in the Hammersley last-passage percolation model with i.i.d. random weights, and the existence, ergodicity and uniqueness of equilibrium (or time-invariant) measures for the related (multi-class) interacting fluid system. As we shall see, in the classical Hammersley model, where each point has weight one, this approach brings a new and rather geometrical solution of the longest increasing subsequence problem, as well as a central limit theorem for the Busemann function.
