引入 DASEP:双重非对称简单排他过程

Introducing DASEP: the doubly asymmetric simple exclusion process

David W. Ash

AI总结:

本文提出受生物过程启发的 DASEP 模型,允许粒子改变种类,研究其在一维格点上的组合性质与平稳概率,并建立其与 ASEP 平稳概率之间的联系。

摘要:

组合数学研究经常探讨非对称简单排他过程(ASEP)。ASEP 受统计力学中的例子启发,涉及多种粒子在格点上运动。在传统 ASEP 中,给定种类的粒子可以移动,但不会改变种类。本文探讨了一种新的组合形式体系,即 DASEP(双重非对称简单排他过程)。DASEP 受生物过程启发,与 ASEP 不同,粒子可以从一种种类转变为另一种种类。本文研究了一维格点上 DASEP 的组合性质,包括相关的生成函数。文中探讨了 DASEP 的平稳概率,并证明了将这些平稳概率与较简单的 ASEP 的平稳概率联系起来的结果。

英文摘要:

Research in combinatorics has often explored the asymmetric simple exclusion process (ASEP). The ASEP, inspired by examples from statistical mechanics, involves particles of various species moving around a lattice. With the traditional ASEP particles of a given species can move but do not change species. In this paper a new combinatorial formalism, the DASEP (doubly asymmetric simple exclusion process), is explored. The DASEP is inspired by biological processes where, unlike the ASEP, the particles can change from one species to another. The combinatorics of the DASEP on a one dimensional lattice are explored, including the associated generating function. The stationary probabilities of the DASEP are explored, and results are proven relating these stationary probabilities to those of the simpler ASEP.
