Query: Derivation of viscous Burgers equations from weakly asymmetric exclusion
  processes   We consider weakly asymmetric exclusion processes whose initial density
profile is a small perturbation of a constant. We show that in the diffusive
time-scale, in all dimensions, the density defect evolves as the solution of a
viscous Burgers equation.
