要：We consider a well-known simplified model for 3D turbulence, the 1D or multi-dimensional potential Burgers equation, with spatially smooth stochastic forcing. We give sharp estimates for small-scale quantities such as increments and energy spectrum, and then we say a few words about the dynamical features of this equation, and in particular the speed of convergence to the stationary measure.
