A variational approach to second order mean field games systems with density constraints: the stationary case

In this work we study second order stationary Mean Field Game systems under density constraints. We show the existence of weak solutions for power-like Hamiltonians with arbitrary order of growth. The...

Una versione astratta della disuguaglianza di Lewy-Stampacchia ed alcune applicazioni

Nel talk discutero' come formulare in maniera astratta, nel setting di spazi vettoriali topologici muniti di una struttura di reticolo, la disuguaglianza classica di Lewy-Stampacchia. Il vantaggio di ...

Derivative-free Methods using Linesearch Techniques

Many real world problems can be modeled as nonlinear optimization problems where the first order derivatives of the objective function and constraints can be neither calculated nor approximated explic...

A Dirichlet problem involving the divergence operator

Given a vector field a and a function f, we want to find a vector field u such that {divu+⟨a;u⟩=f u=0in Ωon ∂Ω. This is a joint work with Gyula Csato....

Evolution of microstructures for a damage model

SEMINARIO DEI DOTTORANDI Starting from the damage model for elastic material introduced by Francfort&Marigo, we will present results that combines efficiently the notion of quasi-static evolution ...

The wonderful structure of graphene

Abstract: The unique electronic properties of graphene have attracted a huge amount of attention since its discovery in 2004. The structural properties of such a two-dimensional lattice are less known...

Invariant measure for the non linear Schrödinger equation on R displaying a local non linearity

We consider the equation on R i∂tu−Δu+χ|u|2u=0 where χ is a smooth function decaying at infinity. The aim of this talk is to build an invariant measure for this equation supported below L2. We will in...

Existence of traveling waves for Lipschitz discrete dynamics: monostable case as a limit of bistable cases

We study discrete monostable dynamics with general Lipschitz non-linearities. This includes also degenerate non-linearities. In the positive monostable case, we show the existence of a branch of trave...
