A few steps in artificial intelligence

Abstract: Artificial Intelligence (AI) has by now become pervasive in our every day life. In this seminar I will provide a very basic introduction to AI, reviewing the underlying ideas and the main mo...

Scudo magnetico per l'equazione di Vlasov-Poisson

Abstract: Riferirò su una ricerca che sto svolgendo con Silvia Caprino (Roma2) e Guido Cavallaro (questo dipartimento). Studiamo un modello matematico di protezione di una navicella spaziale da un ven...

How it happened (to me) to meet ?

The function ? was defined by Minkowski with the purpose of mapping quadratic irrationals bijectively onto the rationals of (0,1) (in addition, it maps the rationals onto the dyadic rationals). It has...

Superfluidity and geometry of Bloch bands

Abstract: Band structure theory and the BCS theory of superconductivity are two cornerstones of modern condensed matter physics. They have been used to explain many properties of crystalline solids an...

Alcuni risultati recenti sui metodi numerici di programmazione dinamica per sistemi ibridi

Negli ultimi vent'anni, il concetto di sistema ibrido ha fornito un solido quadro teorico per unificare una vasta classe di sistemi di controllo, in cui accanto alle azioni di controllo usuali, si uti...

Recurrence properties for random walks on a two-dimensional random graph.

Recurrcnce properties for random walks on a two-dimensional random graph. In [1] a random walk on a bi-dimensional random graph was studied. This model had been previously introduced in the physical l...

POD-Based Multicriterial Optimal Control by the Reference Point Method

In the talk bicriterial optimal control problem governed by a parabolic partial differential equation (PDE) and bilateral control constraints is considered. For the numerical optimization the referenc...

The differential topology of semimetals

Abstract: The "Weyl fermion" was discovered in a topological semimetal in 2015. Its mathematical characterisation turns out to involve deep and subtle results in differential topology. I will outline ...

Differential Privacy applied to common methods of dissemination of frequency tables

When official data are to be disseminated to the public, the agency that releases the data must guarantee $ It is not clear how to define and measure privacy. I will explain a notion developed in comp...
