In my lecture I will illustrate a recent work (in collaboration with J.Bourgain, H.Brezis, A.Figalli) on the characterization of the perimeter and of sets of finite perimeter in terms of a BMO-like seminorm, solving positively a question raised in a…

Low density phases in a uniformly charged liquid – Matteo Novaga (Università di Pisa)
This talk is concerned with the macroscopic behavior of global energy minimizers in the three-dimensional sharp interface Ohta-Kawasaki model of diblock copolymer melts. We are interested in the large volume behavior of minimizers in the low volume…
Asymptotics of interface evolution in random and periodic environment – Nicolas Dirr (University of Cardiff)
A surface moving by mean curvature flow with a rapidly oscillating forcing models e.g. the behaviour of a phase boundary in an impure medium. Mathematically, the combination of rapidly varying random or periodic coefficients and geometric evolution…
