KPZ方程的普适性

Universality of KPZ equation

Patricia Goncalves, Milton Jara

摘要:

我们引入了KPZ方程能量解的概念。在最小的假设下,我们证明了一维弱非对称保守粒子系统相对于定态的密度涨落是由KPZ方程的能量解给出的.因此,我们证明了Cole-Hofp解也是KPZ方程的能量解。

英文摘要:

We introduce the notion of energy solutions of the KPZ equation. Under minimal assumptions, we prove that the density fluctuations of one-dimensional, weakly asymmetric, conservative particle systems with respect to the stationary states are given by energy solutions of the KPZ equation. As a consequence, we prove that the Cole-Hofp solutions are also energy solutions of the KPZ equation.
