Some mathematical questions around the Bose condensation phenomena

I will present briefly the mathematical models describing a dilute Bose gas. Then, explain the Bose condensation from a simple mathematical point of view and give the model describing the system dilut...

Mountain pass: the numerical point of view

The Mountain Pass Theorem is an important tool in the calculus of variations and in finding solutions to nonlinear PDEs in general. It is important not only for the theory but since publishing the Mou...

Movement of hot spots of the heat equations in the exterior domain of a ball

We consider the movement of the set of maximum points of the solution of the heat equation in the exterior domain of a ball, under the Neumann boundary condition. We prove that the set of the maximum ...

Asympotic behavior near the boundary of homogenization periodic problems

The asymptotic behavior of the solutions of an elliptic Dirichlet linear problem, where the coefficients vary periodically has been considered by several authors. However, the classical approximation ...

Problemi variazionali in spazi di Sobolev frazionari a valori in sfere

Si studiano problemi di minimo per applicazioni a valori in sfere con vincoli topologici, concentrandosi sul caso modello H1/2 (S1; S1). In questo caso si affronta il problema di minimo per una famigl...

Sulla localizzazione dei punti di concentrazione nei problemi ellittici singolarmente perturbati

Si discutono alcune condizioni necessarie per la concentrazione di soluzioni, attorno ad un dato punto, di alcune classi di equazioni e sistemi ellittici singolarmente perturbati. Le condizioni coinvo...

Some Remarks on Elliptic Problems with energy going somewhere

We discuss a couple of problems in which after some limit process, or the energy setting has no sense to be considered either the energy is no finite and some different framework must be considered....

Mathematical analysis of semiconductor model

The talk will give a full description of the mathematical analysis of the models arising from semiconductor sciences. Especially, the recent research on both Euler-Poisson system and quantum drift-dif...

Flat level set regularity of p-Laplace phase transitions

I will talk about some recent results obtained in collaboration with E. Valdinoci and V. O. Savin. We consider weak solutions of div(−Du(x)−p−2Du(x))=h0’(u(x)) where h0 is a double-well potential. We ...

Recent Progress on a Singularly Perturbed Semilinear Neumann Problem

In this talk I would like to discuss solutions with maximal number of spikes on a domain, their energy levels and various other related questions for a singularly perturbed semilinear Neumann problem....

Un modello per la crescita eteroepitassiale di un film sottile elastico su substrato elastico

Si studia un problema a discontinuita libera che consiste nella minimizzazione di un funzionale ottenuto come somma di un’energia di volume (energia elastica) e di un’energia di superficie. Tale probl...
