我们重新解释和推广Lam和威廉姆斯关于环上多物种排斥过程的平稳分布的陈述。我们研究的中心对象是法拉利和马丁的多线队列。我们在不同的方向上取得了一些进展。首先,我们通过推广Ferrari-Martin跃迁的速率,证明了Lam和威廉姆斯在两种特殊情况下的定理。其次,我们定义了一个新的多线排队过程,它具有一定的极小性。这给出了一个特殊情况的另一个证明;即三个物种的任意跳跃率。
We reinterpret and generalize conjectures of Lam and Williams as statements about the stationary distribution of a multispecies exclusion process on the ring. The central objects in our study are the multiline queues of Ferrari and Martin. We make some progress on some of the conjectures in different directions. First, we prove Lam and Williams' conjectures in two special cases by generalizing the rates of the Ferrari–Martin transitions. Secondly, we define a new process on multiline queues, which have a certain minimality property. This gives another proof for one of the special cases; namely arbitrary jump rates for three species.
