Abstract Homogenization is a mathematical modelization of composite materials, which gives a meaning to the effective properties of highly heterogeneous materials. It also explains the appearence of a lower order term in the heat or diffusion equation in a domain with many small holes. The main mathematical tools involved are the weak convergence, which allows one to describe the effective behaviour of the various fields which appear in partial differential equations, and the compensated compactness theory.
