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...
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...
Lo Jacobiano di Arakawa è uno dei più noti schemi numerici per l'integrazione dell'equazione di vorticità per flussi bidimensionali incomprimibili. La sua importanza è dovuta alle proprietà mimetiche ...
In questo seminario presenteremo in un'unica formulazione matematica due modelli di riflessione per la risoluzione del problema di Shape-from-Shading nel caso di superfici non Lambertiane (il modello ...
Steiner symmetrization is a very useful tool in the study of isoperimetric inequality. This is also due to the fact that the perimeter of a set is less or equal than the perimeter of its Steiner symme...
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...
