Introduction to the Physics of Random Systems,o distorsions without much surprise. The methods known as homogeneization theory [59] and effective medium theories [135] exemplify this by starting from the concept that an heterogeneous medium can be replaced for all its relevant observables by an effective and equivalent homogeneous medium.

RAGE

The Renormalization Group,ck of spins that one analyzes within the system. The usefulness of the RG approach is based on the existence of scale invariance and self-similarity of the observables at the critical point. The purpose of the RG is to translate in mathematical language the concept that a critical point results from
