摘要：

We show that nonlinear interface growth models with roughness exponent alpha=1 have intrinsic nonperturbative infrared singularities which are inaccessible to the usual dynamical renormalization group analysis. We argue that these infrared singularities give rise to a strong-coupling problem in 1+1 dimensions and provide the underlying reason for the difference between local and global dynamic scaling in these models.
