Basic knowledge of the theory of Sobolev spaces and Functional Analysis
1. General theory
2. Localization tools
3. Local integral functionals on Sobolev spaces
5. Perforated domains and relaxed Dirichlet problems
6. Phase transition and concentration problems
7. Free discontinuity problems
Educational goals: The theory of Gamma-convergence, introduced by E.De Giorgi in the 70', provides the natural language to study limits of variational problems. By now it is a mature theory, with a broad range of applications (homogenization, phase transitions, discrete-to-continuum approximations). The course will be based mainly on the discussion of paradigmatic examples and applications, after a preliminary discussion of the basic aspects of the theory.
