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...
In this talk we consider a spatial version of the Marcus-Lushnikov process, which models the evolution of particles that merge pairwise in a series of coagulation events. The particles are equipped wi...
Let \( G \) be a simple algebraic group and \( \mathcal O \subset \mathfrak g = Lie(G) \) a nilpotent orbit. If \( H \) is a reductive subgroup of \( G \), then \( \mathfrak g = \mathfrak h \oplus \ma...
In operator algebra theory central sequences have long played a significant role in addressing problems in and around amenability, having been used both as a mechanism for producing various examples b...
