Title: Dynamics, fractal geometry and the exponents of the Kardar-Parisi-Zhang equation

Abstract
The KPZ equation [1] is connected to a large number of processes, such as atomic deposition, evolution of bacterial colonies, the direct polymer model, the weakly asymmetric simple exclusion process, the totally asymmetric exclusion process, direct d-mer diffusion, fire propagation, turbulent liquid-crystal, spin dynamics, polymer deposition in semiconductors, and etching [2]. We present a short review of the field, with some modern problems and perspectives. We discuss as well how a new interpretation of the fluctuation-dissipation theorem [3] allows us to give a solution for the KPZ exponents [4].
