### Abstract

The equation u
_{t} = Δu + μ|∇u|, μ ∈ ℝ, is studied in ℝ
^{n} and in the periodic case. It is shown that the equation is well-posed in L
^{1} and possesses regularizing properties. For nonnegative initial data and μ < 0 the solution decays in L
^{1}(ℝ
^{n}) as t → ∞. In the periodic case it tends uniformly to a limit. A consistent difference scheme is presented and proved to be stable and convergent.
