Recent and up-coming seminars

High Performance Combinatorics

-- Florent Hivert (Université Paris-Sud)

partly joint with Jean Fromentin In this talk, I will report on several experiments around large scale enumerations in enumerative and algebraic combinatorics. In a first part, I'll present a small framework implemented in Sagemath allowing to perform map/reduce like computations on large recursively defined sets. Though it ...

Polytopal Realizations of Finite Type g-Vector Fans

-- Salvatore Stella (University of Haifa, Israel)

To any cluster algebra with principal coefficients A, and by extension to any other cluster algebra, it is associated a simplicial fan that encodes the underlying combinatorial structure: the g-vector fan. When A is of finite type, this fan has a natural interpretation in terms of a (not necessarily finite ...

Limite d'échelle des permutations séparables : description et universalité du permuton séparable Brownien

-- Mickaël Maazoun (UMPA, ENS Lyon)

Travaux en collaboration avec F. Bassino, M. Bouvel, V. Feray, L. Gerin et A. Pierrot. Le permuton séparable Brownien a été introduit par Bassino et. al. (2016) comme la limite d'échelle des permutations séparables. C'est une mesure aléatoire sur le carré unité, construite à partir d'une excursion ...
