Abstract
We consider the evolution by crystalline curvature of a planar set in
a stratified medium, modeled by a periodic forcing term. We characterize the
limit evolution law as the period of the oscillations tends to zero. Even if the
model is very simple, the limit evolution problem is quite rich, and we discuss
some properties such as uniqueness, comparison principle and pinning/depinning
phenomena
