Title: Gamma convergence results for non-local energies

Abstract: In this seminar I will speak about the problem of the variational approximation of free discontinuity functionals, which have an important role in many variational problems recently under consideration (computer vision, fracture mechanics, plasticity and so on) by means of non-local type energies. The main difficulty is to recover the surface part in the Gamma limit, and this problem seems to be very hard in the linear growth case.
