This talk is based on a joint work with Michael Ruzhansky and it is devoted to proving the global solvability of the Cauchy problem for the Kirchhoff equation in the Gevrey space. More precise results are derived for solutions in the s-Gevrey…

Non-local isoperimetric problems – Berardo Ruffini (CMAP, Ecole Polytechnique)
The talk is aimed to present some recent results about strong version of non-local isoperimetric isoperimetric problems, that is, problems involving the minimisation of the fractional perimeter. Namely, we will see how to prove a strong version of…
On some minimization problems in R^N: choice of constraints, Lagrange multipliers and the concentration-compactness principle revisited. – Mihai Maris (Univ. Toulouse)

Bifurcation and stability of solitons for the asymptotically linear NLS – François Genoud (Delft Institute of Applied Mathematics)
“Abstract”:The purpose of this talk is to convey the idea that bifurcation theory provides a powerful tool to prove existence and orbital stability of solitons for the nonlinear Schrödinger equation. It is especially useful to obtain results for…

Hamiltonian systems of Schroedinger equations with supercritical exponential growth – Daniele Cassani (Università degli Studi dell’Insubria)
We present existence of solitary waves solutions for elliptic systems in dimension two with nonlinearities which exhibit supercritical growth with respect to the critical growth prescribed by the Pohozaev-Trudinger-Moser inequality. We obtain…

Characterizations of sets of finite perimeter: old and recent results – Luigi Ambrosio (Scuola Normale Superiore)
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…
