Chambolle:
In this talk I will discuss results on the effective surface
tension obtained by homogenization of periodic perimeters. I'll present
older results in collaboration with M. Goldman and M. Novaga, and more
recent results, in the discrete setting, on the differentiability and
crystallinity of the effective surface tension. I will also discuss the
construction of "optimal" periodic patterns for reaching some criterion.http://cvgmt.sns.it/seminar/824/
