| الوصف: | The multispecies asymmetric simple exclusion process (mASEP) is a Markov chain in which particles of different species hop along a one-dimensional lattice. This paper studies the doubly asymmetric simple exclusion process $\mathrm{DASEP}(n,p,q)$ in which $q$ particles with species $1, \dots, p$ hop along a circular lattice with $n$ sites, but also the particles are allowed to spontaneously change from one species to another. In this paper, we introduce two related Markov chains called the colored Boolean process and the restricted random growth model, and we show that the DASEP lumps to the colored Boolean process, and the colored Boolean process lumps to the restricted random growth model. This allows us to generalize a theorem of David Ash on the relations between sums of steady state probabilities. We also give explicit formulas for the stationary distribution of $\mathrm{DASEP}(n,2,2)$. Comment: 15 pages, 5 figures |
