平稳TASEP两点函数的收敛性

Convergence of the two-point function of the stationary TASEP

Jinho Baik, Patrik L. Ferrari, Sandrine Péché

摘要:

本文研究了具有平稳初始条件的完全非对称简单排斥过程的两点函数。两点函数可以表示为相关高度函数的方差的离散拉普拉斯算子。适当缩放的高度函数的分布函数的极限先前由Ferrari和Spohn获得。在本文中,我们证明了收敛性可以改进为矩的收敛。这意味着当时间趋于无穷大时,两点函数在弱意义上沿着近特征方向收敛,从而证实了Ferrari和Spohn的论文中的猜想。

英文摘要:

We consider the two-point function of the totally asymmetric simple exclusion process with stationary initial conditions. The two-point function can be expressed as the discrete Laplacian of the variance of the associated height function. The limit of the distribution function of the appropriately scaled height function was obtained previously by Ferrari and Spohn. In this paper we show that the convergence can be improved to the convergence of moments. This implies the convergence of the two-point function in a weak sense along the near-characteristic direction as time tends to infinity, thereby confirming the conjecture in the paper of Ferrari and Spohn.
