Travelling waves in spatially heterogeneous media

We consider travelling waves in spatially recurrent diffusive media, including the almost periodic and quasi-periodic ones as special cases. We first define the notion of travelling waves under such h...

The boundary behaviour of blow-up solutions related to state constrained problems

We study the asymptotic behaviour near the boundary of explosive solutions of a viscous Hamilton-Jacobi equation. This model was introduced by J.M. Lasry and P.L. Lions from a state constrained proble...

Sulla classificazione delle soluzioni dell’equazione di Lane-Emden in domini non limitati

Lo scopo del seminario e di presentare alcuni recenti risultati riguardanti le soluzioni dell’equazione di Lane-Emden in domini non limitati dello spazio euclideo ad N dimensioni. In particolare, si p...

Limitazioni per i minimi vettoriali di alcuni funzionali

Nell’ambito dei funzionali integrali del calcolo delle variazioni, stime puntuali per i minimi sono ben note nel caso scalare. Nel caso vettoriale, il controesempio di De Giorgi pone forti vincoli. No...

PDE aspect of extremal metrics

I will present some recent joint work with C. Arezzo and M. Singer concerning the existence of extremal metrics in Kahler geometry. The problem reduces to some perturbation result for some fouth order...

Multiple solutions to semilinear elliptic problems via flow invariance and topological methods

I will discuss some recent results on the existence of multiple solutions to equations of the form −∆u = f(x, u), where the nonlinearity f has subcritical or critical growth. In some cases we find sig...

How the boundary conditions affect the attainability of the optimal constant of some Caffarelli-Kohn-Nirenberg inequalities. Some applications.

In this talk, will be presented some results on the optimal constants of Sobolev and Hardy-Sobolev inequalities with weights and their relation with the behavior of some mixed Dirichlet-Neumann bounda...

Smoothing problems for dispersive equations and global analysis of Fourier integrals

We will review smoothing problems for dispersive equations, in particular for the Schrodinger equation. We will relate these problems to the global analysis of certain Fourier integrals, spectral prob...

Comportamento asintotico dell’equazione di reazione-diffusione stocastica

Si considera l’equazione di reazione-diffusione con potenziale a due pozzi in un intervallo finito con termine forzante aleatorio. Si scelgono condizioni al bordo di Dirichlet non omogenee che impongo...

Noncompact optimal transport

The problem of Optimal Mass Transport, due to Monge,is to transfer a mass from one location to another trying to minimize a total cost. The case where the cost is the square of the distance on the Euc...
