In this talk, we will present recent results on using existing 3D printer hardware to reproduce the look of physical materials. We will show that 3D printing can be seen as an optimization approach an...
The recent literature has introduced models based on nonlocal conservation laws in several space dimensions, e.g., see [3] for crowd dynamics applications or [1] for sedimentation processes. The Lax-F...
I will present a variational time discretization for the multi-dimensional gas dynamics equations, in the spirit of minimizing movements for curves of maximal slope. Each timestep requires the minimiz...
In questo seminario presenterò una nota approssimazione semi-Lagrangiana per equazioni di Hamilton-Jacobi del secondo ordine, introducendo alcune modifiche e combinando alcuni concetti chiave che perm...
In this talk we are interested in asymptotic behavior of singularly perturbedcontrol system in the non-periodic setting. More precisely, we consider the value function of finite horizon optimal contro...
We study the theory of Scattering in the energy space for various nonlinear Schr?dinger equations. In dimension 3 or bigger we consider a variable coefficients equation, for a gauge invariant, defocus...
In this talk, I will present the concentration profile of various kind of symmetric solutions of some semilinear elliptic problems arising in astrophysics and in diffusion phenomena. Motivated by thes...
Abstract: A beam of light is characterized by the following local properties: intensity, phase, and polarization. In most practical cases, these optical properties are either uniform or varying in spa...
(seminario rivolto prevalentemente ai docenti delle Superiori; i docenti sono invitati a portare un generatore di numeri casuali; spesso è disponibile anche nei cellulari)...
I will present and discuss some results and problems about flows of metrics on Riemannian manifolds correlated to Ricci flow: - The "renormalization group" flow, truncated at the second order term. Th...
