Zubov's method is a technique to characterize the domain of attraction of locally asymptotically stable equilibria of an ordinary differential equation (ODE) as the sublevel set of an appropriate Hami...
We show that the combined action of similarity and symmetry produces 2D finite differences (2D dynamics) in the limit of 1D finite differences (1D dynamics). This provides a construction of the 2D Lap...
We study a discounted infinite horizon control problem in a stratified setting. We write down an appropriate Hamilton-Jacobi-Bellman equation and prove a comparison principle implying that the value f...
In this talk we address the solution of quasilinear elliptic problems of monotone type by using the Mimetic Finite Difference (MFD) method. Under a suitable approximation assumption, we prove that the...
We derive optimal order a posteriori error bounds for a fully discrete Crank-Nicolson finite element scheme for linear Schroedinger equations. The derivation of the estimators is based on the reconstr...
Il modello quasi-geostrofico è uno tra i piè semplici modelli volto alla descrizione della circolazione atmosferica per i flussi a larga scala extra-tropicali (scale sinottiche). Presenterò il modello...
In this talk an a-posteriori error analysis for optimal control problems is discussed. In particular, the error analysis is applied to reduced-order Galerkin approximations for the optimal control pro...
The term "resource curse phenomenon" refers to countries with an abundance of natural resources, in particular nonrenewable ones such as minerals or fuels, that tend to have less economic growth and w...
Tecniche abbastanza classiche (interpretabili in un quadro di calcolo stocastico) permettono di trattare termini diffusivi in forma di traccia negli schemi SL. Verrà discussa una estensione di queste ...
Shape-from-Shading and Photometric Stereo are two fundamental problems in Computer Vision aimed at reconstructing surface depth given either a single image taken under a known light source or multiple...
