We will introduce the Stolz sequence and explain how it plays a role in the study of metrics with positive scalar curvature. We shall then extend it to two different contexts: that of (G, F)-spaces, i...
This third session of Round Meanfield will be devoted to a large scope of new phenomenologies arising in the field of collective motion for systems of large number of different kinds of "objects...

Hopf algebras (and variations of them) are the algebraic counterpart of (strict, rigid) tensor categories. As such, they appear as symmetries of different categorial, geometrical, and physical objects...
We will review some theory of algebraic groups over Q_p and the construction of the Bruhat-Tits building for a split group G over Q_p. At the end, we will see some applications and mention some result...
To any vertex algebra one can attach invariants of different nature: its automorphism group, its character (a formal series), its associated variety (a Poisson variety), etc. In this talk, I will exp...
They say it's hard to compute an isogeny between any two elliptic curves, and yet they spend their time computing them. Isogeny people have played us for absolute fools! What does "compute" even mean...
A C*-algebra is often considered as non-commutative space, which is justified by the natural duality between the category of unital, commutative C*-algebras and the category of compact, Haus...
I will introduce the basic principles of the geometric approach to symmetric-key cryptanalysis, first from a general and then from a more concrete point of view. In the main part of the talk, I will s...
Diversi cifrari a flusso di interesse applicativo, come Trivium ed E0 del Bluetooth, possono essere modellizzati come sistemi di equazioni (ordinarie esplicite) alle differenze a coefficienti e soluzi...
