Cari colleghi,

vi comunichiamo che domani, mercoledi' 18 dicembre alle ore 16.00 nell'aula seminari, presso il Dipartimento di Matematica (Univerista' di Pisa), il Prof. Alexander Plakhov (University of Aveiro, Portugal) presentera' un seminario dal titolo:

"Besicovitch's magic method and problems of minimal resistance"

Abstract: see attached file.

e alle ore 17.00 il Prof. Enrico Valdinoci (WIAS Institute, Berlin) presentera' un seminario dal titolo:

"Regularity of nonlocal minimal surfaces in low dimension"

Abstract: We present a full-detail proof of the fact that the only minimal cones for the nonlocal perimeter in plane are the trivial ones (equivalently, the singular set of fractional perimeter minimizers has, at most, codimension three).
As a consequence, we show that a Bernstein type result holds in this setting up to dimension three.
The technique used is quite flexible and it may be applied to obtain monotonicity and symmetry results for variational problems with quadratic energy growth. These results were obtained in collaboration with O. Savin and A. Figalli.
