Costanti ottimali in disuguaglianze di Moser-Trudinger e equazioni di Liouville singolari

Consideriamo un'equazione di Liouville su superfici compatte motivata dallo studio di modelli di Chern-Simons autoduali e dal problema di prescrizione della curvatura Gaussiana con singolarità coniche...

Shape optimization problems for variational functionals under geometric constraints

We consider extremum problems for some classical functionals of the Calculus of Variations (such as torsional rigidity, first Dirichlet eigenvalue, electrostatic capacity), subject to geometric constr...

Osservazioni sulla dinamica di certe equazioni di tipo forward-backward

If \phi:R\to R is a non-convex energy density, the initial-boundary value problem for the equation (1) \begin{equation} \left\{ \begin{array}{ll} u_t+\frac{1}{2}(\phi(u_x))_x,x\in(0,1) \\ u(\cdot,0)=u...

Equazioni di Hamilton-Jacobi su grafi

Equazioni alle derivate parziali su grafi hanno numerose applicazioni (per esempio modelli di traffico, circolazione del sangue, social networks, internet, etc.). In molti di questi problemi e' import...

Semiclassical limit of linear Schrodinger equation with singular and rough potentials

We describe some recent work on the semiclassical limit of the linear Schrodinger equation. Under mild regularity assumptions on the potential U which include Born-Oppenheimer potential energy surface...

What can be estimated by the L^1 norm of some components of the derivatives of a vector field?

Given a vector homogeneous differential operator of order 1 A(D) acting on vector fields, I will answer to the question whether there is a Gagliardo--Nirenberg type estimate of the form ||u||_{L^{n/(n...

One-dimensional symmetry for solutions of Allen Cahn fully nonlinear equations

In this talk we shall present some qualitative results for solutions of the fully nonlinear elliptic Allen Cahn Equation; precisely we shall see that under specific conditions the solutions are one-di...

Il problema isoperimetrico rispetto ad una densità simmetrica

Dopo aver rivisto alcuni risultati di base e alcuni problemi aperti sul problema isoperimetrico nello spazio Euclideo con densità, discuteremo il caso modello di densità di tipo misto Euclideo-Gaussia...

Capacity estimates of solutions of semilinear parabolic equations

We prove that any positive solution of \partial_t u-\Delta u+u^q=0 (q>1) in R^N \times (0,\infty) with singular initial trace (F,0), where F is a closed subset of R^N can be represented, up to two ...

Some new quantitative spectral inequalities

In last years, there has been some effort to get quantitative versions of the most classical spectral inequalities, namely the Faber-Krahn inequality for the first eigenvalue of the Dirichlet Laplacia...
