The Passage From Discrete Systems to Continuous Variational Problems

Andrea Braides

These notes contain material related to the five lectures that I have delivered at the University of Utah in the week 16--20 May 2005. They are organized in the order of the lectures; namely,

1. Spin systems. An introduction to lattice systems

2. Limits of finite-difference lattice systems.

3. Bounds for linear networks.

4. A model for a membrane with randomly-distributed defects.

5. Derivation of fracture energies from inter-atomic potentials.
 

The notes are thought just as a complement and reference for the single lectures, and not as a whole: I must warn that the chapters are unevenly written. Some are elaboration of articles that have already appeared and some have been completely written for the occasion. As a consequence some notation may slightly vary from chapter to chapter.
