Counter-example in three dimension and homogenization of geometric motions in two dimension (Q2453973)

The authors focus their attention on giving a counter-example to the homogenization of the forced mean curvature motion in a periodic framework when the space dimension satisfies \(N\geq 3\) and the forcing is positive. They also present a generalization for the case \(N=2\), where they allow for changes of sign in the normal velocity.
