Krylov Methods for the Approximation of Matrix Functions

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...

Teoria quantistica del controllo: motivazioni, metodi, risultati"

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...

A link between microscopic and macroscopic models of self-organized aggregation

In order to understand self-organized aggregation of German cockroaches which possess aggregation pheromone, we propose an individual-based model where each individual with social interaction moves by...

Approssimazione di misure di probabilità soluzioni di modelli di comportamento collettivo

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...

Approssimazioni monotone per problemi di controllo ottimo di sistemi ibridi

La nozione di sistema di controllo ibrido è stata proposta in tempi relativamente recenti per dare un quadro unificato a molti sistemi di controllo di forte interesse applicativo, caratterizzati dal f...

Uno schema Semi-Lagrangiano per il moto per Curvatura media e sue estensioni

Presenterò uno schema Semi-Lagrangiano per il moto per curvatura media. L'approssimazione si ottiene accoppiando un metodo stocastico per l'approssimazione delle caratteristiche, da intendersi in modo...

How to find a minimum of a multivariate convex function only by its values

Is it possible to compute effectively the minimal value of a multivariate function without computing its derivative? The general answer is "No", unless the function is convex. For convex functions one...

An efficient policy iteration algorithm for dynamic programming

Policy iteration is a well-known alternative to algorithms based on value function iterations for the solution of optimal control problems and differential games. In this talk we present a scheme for ...

Hyperbolic Models for Granular Matter Dynamics

The Savage-Hutter and the Hadeler-Kuttler equations can be used to describe the movement of granular matter. The former, in its standard formulation, neglects erosion/deposition phenomena. The latter ...

A semi-Lagrangian scheme for the game p-Laplacian

We present and analyze a numerical approximation of the two-dimensional Dirichlet problem for the game p-Laplacian based on a semi-Lagrangian scheme. We start from recalling the definition of game p-L...

New results in differential inclusion theory

We will present a relatively new approach to differential inclusion theory that is "parametrization-free". That is, results in control theory will be described under assumptions on the Hamiltonian (an...

Pursuit-Evasion Games with Multi-Pursuer: a decomposition approach

In a pursuit-evasion game, each pursuer attempts to minimize the distance between the pursuer (P) and the evader (E) and capture it in the shortest time, whereas the evader tries to maximize the dista...
