Action de sl(2) sur les mousses et les homologies de Khovanov--Rozansky.

Louis-Hadrien Robert (UCA)

11/09/2025    
11h00 - 12h00
Dans cet exposé, après avoir rappelé les motivations et la définition des homologies de Khovanov--Rozansky, j'expliquerai en quoi l'approche mousseuse de ces homologies permet de [...]

Inhibitive Hawkes processes and cumulative processes

Laetitia COLOMBANI (Université Lyon 1)

Hawkes process was introduced by Hawkes in 1971 and are widely used in many applications (earthquakes, neurons, social network, finance, etc.). This jump process has [...]

Speed limits of time almost periodic traveling waves for rapidly/ slowly oscillating reaction-diffusion equations

Ding Weiwei ( )

This talk is concerned with the wave propagation dynamics of time almost periodic reaction-diffusion equations. Assuming the existence of a time almost periodic traveling wave [...]
Invariants énumératifs réels relatifs

Invariants énumératifs réels relatifs

Ilia Itenberg (IMJ-PRG)

L'exposé est consacré à plusieurs problèmes énumératifs réels et tropicaux. Nous proposons de nouveaux invariants énumératifs réels du plan projectif (et, plus généralement, de certaines [...]

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 [...]

∞-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 [...]
