Homogeneization is the mathematical study of problems with parameters oscillating on a small scale with respect to the size of the problem, in order e.g. to obtain effective models for composite materials. In the case of periodic homogeneization, Cioranescu, Damlamian and Griso have developed the powerful unfolding method.

Nicolas Meunier and I have applied this method to nonlinear elliptic problem. In collaboration with Alain Damlamian we have extended the results to the case of maximal monotone graphs and subdifferentials of convex functions.
