After reviewing the combinatorial definition of meanders, I will discuss a simple random matrix model that is governed by the same combinatorial objects. If time allows, I will discuss the question of the rank of …

This session will be dedicated to the introduction the elements of toric geometry required in the statement and proof of the conjecture.

Description : Cette formation a pour but de présenter les problématiques de l’apprentissage supervisé et du clustering, et les méthodes les plus classiques pour chacune. Objectifs : A la fin de la formation, vous …

On se propose d'expliquer l'historique de la théorie des séries aléatoires de fonctions propres (concernant l'étude de leur convergence uniforme) depuis les travaux de Paley-Zygmund (1930) jusqu'à des développements …

In biomathematics, the Hele-Shaw problem can be applied to simulates that the cell (bacterium) diffusion is governed by the stiff pressure law. The modeling of Hele-Shaw problem with nonlocal aggregation effect is …

Since the 1980s, it has been well known that there is a close relationship between two-dimensional conformal field theories and three-dimensional topological field theories. This CFT/TFT correspondence provides a …

The aim of this presentation is to introduce generative models based on diffusions. After a brief review of the key concepts of stochastic calculus and PDEs, we will detail how the time-reversed Ornstein-Uhlenbeck …
