Homogenization is by now a classical method to simplify models featuring fine microstructure. In the case of integral functionals on Sobolev spaces, the form of simplification depends drastically on whether the integrand is convex or not. For non-convex integrands, the homogenized integrand is given by a complicated multi-cell involving a minimization problem on larger and larger cubes. In this ta
