摘要:

研究格点{1,…,n}上开式非对称简单排斥过程(ASEP)的平稳测度。固定跃迁速率并令n趋于无穷时,该测度收敛于半无限格点上的测度。在高密度相与低密度相中,我们刻画了极限测度的性质,并给出总变分距离下收敛速率的界。研究方法为利用生成函数估计总变分距离,再通过对Askey-Wilson带号测度的原子质量进行精细分析来估计生成函数。

英文摘要:

Consider the stationary measure of open asymmetric simple exclusion process (ASEP) on the lattice $\{1,\dots,n\}$. Taking $n$ to infinity while fixing the jump rates, this measure converges to a measure on the semi-infinite lattice. In the high and low density phases, we characterize the limiting measure and provide bounds on the convergence rates in total variation distance. Our approach involves bounding the total variation distance using generating functions, which are further estimated through a subtle analysis of the atom masses of Askey-Wilson signed measures.
