Collective phenomena in immune systems

 Abstract: The immune system defends us from pathogens. But what is an antigen? Does each lymphocyte really know the complete ensemble of all the molecules of our body? Is there, instead, a syste...

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 ...

Higher Order Elliptic Problems in Non-Smooth Domains

We discuss sharp continuity and regularity results for solutions of the polyharmonic equation in an arbitrary open set. The absence of information about geometry of the domain puts the question of reg...

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...

On growth of Sobolev norms of solutions to time-dependent Schroedinger equations

Let us consider the linear Schroedinger equation on the torus with a time dependent Gevrey potential. We shall show that the H^s norm of the solution grows at most logarithmically. This extend the res...

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...

Disuguaglianze di tipo Moser-Trudinger con pesi ed equazioni di Liouville con dati singolaris

L'analisi dell' equazione di Liouville con dati singolari suggerisce naturalmentre lo studio di una disuguaglianza di tipo Moser-Trudinger con peso. Dopo una introduzione al problema e alle sue motiva...

Numerical Methods for Hyperbolic Differential Equations for Applications in Computer Vision

After an introduction on partial differential equations (PDEs), I will visit some classic and modern problems in Computer Vision that are formulated using hyperbolic PDEs. Specifically, these are shap...

Critical point at Infinity approach to Liouville Equations

We consider critical and supercritical Liouville equations on surfaces and on domains of \mathbb{R}^2 under Dirichlet boundary conditions. Using some tools of the "critical point theory at Infinity" o...

A finite volume approximation of a 2 Layer system for growth of sandpile based on schemes for discontinuous flux for hyperbolic conservation laws

We propose an explicit finite volume numerical scheme for a system of partial differential equations proposed in by K. P. Hadeler and C. Kuttler, a model for growing sandpiles under a vertical source ...
