We study the asymptotic behaviour, as the mesh size tends to zero, of a class of discrete energies under very general assumptions that cover the case of bounded and unbounded spin systems, leading to variational limits of integral type. The cases of homogenization and of non-pairwise interacting systems (e.g. multiple-exchange spin systems) are also discussed.

Abstract
We study the asymptotic behaviour, as the mesh size tends to zero, of a class of discrete energies under very general assumptions that cover the case of bounded and unbounded spin systems, leading to variational limits of integral type. The cases of homogenization and of non-pairwise interacting systems (e.g. multiple-exchange spin systems) are also discussed.File in questo prodotto:
