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...
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...
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...
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...
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...
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...
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"....

Diffusion of knowledge models in macroeconomics describe the evolution of an interacting system of agents who perform individual Brownian motions (this is internal innovation) but also can jump on top...
