摘要：

We propose a simple method to compute the velocity difference statistics in forced Burgers turbulence in any dimension. Within a reasonable assumption concerning the nucleation and coalescence of shocks, we suggest, particular, that the ''left'' tail of the distribution may decay as an inverse square power, which is compatible with numerical data. Our results are compared to those of various recent approaches: instantons, operator product expansion, and replicas.
