Abstract: As we learnt from Young and Laplace, the cohesion of fluids makes them choose specific shapes, in particular spheres at a small scale. We discuss several ways to maintain this ideal shape on...
We introduce and study the evolution by horizontal mean curvature flow in Carnot-Carathe'odory spaces. The main difficulty occurs because of the existence of characteristic points, which are points wh...
Abstract: Wetting phenomena at "small" scales (a water drop on a glass, the precorneal tear-film) may be described by quite a few different mathematical models: diffuse interface ones, sharp ones such...
I teoremi adiabatici sono stati recentemente utilizzati in alcuni risultati di controllabilità quantistica. Dopo aver introdotto brevemente i metodi adiabatici (in particolare i teoremi di Kato e di N...
Lo scopo del seminario è introdurre alcuni aspetti della modellizzazione e del controllo dei sistemi quantistici, e discutere alcuni risultati matematici sulla controllabilità quantistica. Sebbene par...
The need to evaluate expressions of the form f(A)v or v'f(A)v, where A is a large sparse or structured matrix, v is a vector, f is a nonlinear function, and ' denotes transposition arises in many appl...
In questo seminario considereremo modelli differenziali del primo ordine per il comportamento collettivo di gruppi di individui interagenti, quali folle, stormi, aggregati cellulari, basati sul princi...
In this talk we present a new unified approach of general P_N P_M schemes on unstructured meshes in two and three space dimensions for the solution of time-dependent partial differential equations ari...
Abstract: Language dynamics is an emerging field that focuses on all processes related to the emergence, evolution and extinction of languages. Recently the study of the self-organization and evolutio...
We consider the problem of minimum distortion intrinsic correspondence between deformable shapes, many useful formulations of which give rise to the NP-hard quadratic assignment problem (QAP). Previou...
Nonostante gli schemi SL classici siano formulati in modo da non garantire la conservazione della massa, varianti conservative degli schemi SL sono state proposte da una quindicina di anni a questa pa...
In this talk we will present some recent results on a posteriori error estimation for the Stokes problem. The error estimator is fully computable and present a robust and rigorous bound for the error,...
