We argue that symmetries and conservation laws greatly restrict the form of the terms entering the long wavelength description of growth models exhibiting anomalous roughening. This is exploited to show by dynamic renormalization group arguments that intrinsic anomalous roughening cannot occur in local growth models. However, some conserved dynamics may display superroughening if a given type of term is present.
我们认为，对称性和守恒定律极大地限制了进入表现出反常粗化的生长模型长波描述的项的形式。利用动态重整化群论证表明，在局部生长模型中不会出现固有反常粗化。然而，如果存在特定类型的项，一些守恒动力学可能会表现出超粗化。
