We consider two models of random walks on a random rough surface. In the first case, the growth and fluctuations of the surface are described by the Edwards–Wilkinson linear model, in the second case, they are modelled by the nonlinear Kardar–Parisi–Zhang equation. Despite the nonlinearity of the second model, ordinary perturbation theory gives us trivial critical dimensions and the only way to get nontrivial results is to take into account nonperturbative effects
