摘要
本文首先介绍KPZ (Kardar-Parisi-Zhang)普适类的物理背景,其中, Eden模型、黏性落体模型和KPZ方程这几类物理模型将被提及;其次,将考察一维KPZ方程的Cole-Hopf解以及几类收敛到一维KPZ方程的离散模型(如角落生长模型和定向聚合物模型等).
In this survey, we shall ?rst introduce the physical background of KPZ universality class. The Eden model, sticky block model and KPZ equation will be mentioned. Then we shall focus on the Cole-Hopf solution to 1-dimensional KPZ equation and present some discrete models like the corner growth model and directed polymer model, which could converge to the KPZ equation in some sense.
