On the Bloch–Kato Conjecture for some four-dimensional symplectic Galois representations

Naomi Sweeting (Princeton)

The Bloch–Kato Conjecture predicts a relation between Selmerranks and orders of vanishing of L-functions for certain Galoisrepresentations. In this talk, I’ll describe results towards thisconjecture [...]

Bernstein—Sato theory in positive characteristic and Frobenius invariant nearby cycles

Hiroki Kato (IHES)

I will talk about how to formulate (and outline an idea of a proof of) a positive characteristic analogue of the theorem of Kashiwara and Malgrange [...]

Representations of GL_2 over Z/p^n Z, hypergeometric polynomials and binomial congruences

Kartik Prasanna (University of Michigan)

Let R = Z/p^n Z. The representation theory of GL_2 (R) over R-modules is well studied for n=1 but there is not much known for n>1. In [...]

Non-linear model order reduction of transport-dominated problems with shifted proper orthogonal decomposition (sPOD) using machine learning methods.

Shubhaditya Burela (...)

Parametric model order reduction techniques often struggle to capture transport-dominated phenomena because the Kolmogorov n-width decays slowly. To tackle this issue, we introduce a data-driven [...]

LLN and CLT in high dimensions for the random walk on the symmetric exclusion process

Rémy Poudevigne (...)

The random walk on the exclusion process is an example of random walk in dynamic environment. In this specific model, the law of the movement [...]

Modular orbifolds and derived Galois deformation theory 

Patrick Allen (McGill University)

An example of Serre shows that in the strong form of his modularity conjecture, one can't always ask for minimal nebentypus. Serre and Carayol independently [...]

Séminaire Rauzy: Géométrie projective, dégénérescences et corps non-archimédiens

Xenia FLAMME (IHES)

20/06/2025    
11h00 - 12h00
Les variétés projectives convexes sont munies d’une métrique naturelle: la métrique de Hilbert. C'est une distance définie sur un ouvert convexe et borné de l’espace [...]

∞-categorical models of linear logic

Elies Harington (LIX & LIPN)

The notion of categorical model of linear logic is now well studied and established around the notion of linear-non-linear adjunction, which encompasses the previous notions [...]

Averages of SL(2, R) automorphic kernel and arithmetic applications

Lasse Grimmelt (Université d'Oxford)

13/06/2025    
11h00 - 12h00
Counting integer solutions to equation with SL2 symmetry (ad-bc=h in the easiest case) is a surprisingly deep and important problem in analytic number theory. In [...]

Poincaré-Hopf Theorem and Chern-Schwartz-MacPherson classes

Thuy Nguyen (Sao Paulo State University)

12/06/2025    
11h00 - 12h00
We redefine the Chern-Schwartz-MacPherson classes using Lipschitz stratifications instead of Whitney stratifications. The obtained class is the same class as the Schwartz' class but the [...]

Maladies tropicales négligées : histoire, enjeux actuels et perspectives futures pour la recherche

Guillaume LINTE (MESOPOLHIS / I2M)

Guillame Linte vient d’être recruté par le CNRS pour 5 ans sur une chaire de Professeur Junior. Il est rattaché principalement au laboratoire MESOPOLHIS, qui [...]

Systèmes dynamiques à grande échelle : méthodes d'approximation par faible rang

Benjamin Carrel (...)

10/06/2025    
11h00 - 12h00
La simulation de systèmes dynamiques à grande échelle est souvent très coûteuse en temps de calcul et en mémoire. Récemment, plusieurs méthodes pour compresser dynamiquement [...]

Getting thin spans in order

Victor Blanchi (LIS, Aix-Marseille)

Recently, Clairambault and Forest introduced the cartesian closed bicategory of thin spans of groupoids. It is a proof-relevant denotational model, akin to Fiore et al's [...]
