2020.04.30 Hubert Lacoin - The scaling limit for directed polymers in an alpha-stable environment
Directed polymers in a random environment is a model of statistical mechanics introduced in the 80s. Given a set of independent, identically random variables $\eta_{n,x}$ indexed by $\mathbb N\times \mathbb Z^d$, and a parameter $\beta⋗0$, it is defined as the measure on the set of nearest

Dominique Manchon - Hopf-Algebraic Renormalization of Multiple Zeta Values and their q-analogues
After a brief introductory account, I’ll explain how a quasi-shuffle compatible definition (by no means unique) of multiple zeta values can be given for integer arguments of any sign, through Connes-Kreimer’s Hopf-algebraic renormalization. Finally, I’ll introduce the Ohno-Okuda-Zudilin mo
