We give an elementary introduction to Rauzy-Veech induction on the space of interval exchange transformations (IETs). We illustrate its „renormalization“ mechanism using simple examples and discuss its relationship …

The Chamanara surface $X$ is an especially interesting translation surface. It has finite area but infinite genus and a wild singularity and its Veech group $\Gamma(X)$ is almost the free group in two generators. …

We discuss the numerical solution of scalar time-harmonic wave equations on unbounded domains which can be split into a bounded interior domain of primary interest and an exterior domain with separable geometry. To …

La formation a pour objectif de présenter les bases de la programmation R. Elle s'adresse aux débutants. Objectifs : A la fin de la formation, vous serez capable de manipuler les différents objets de R, de créer des …

Nous commencerons par rappeler quelques inégalités classiques pour les hypersurfaces de l'espace euclidien dont le cas limite a lieu uniquement pour les sphères géodésiques (comme la majoration de Reilly de la …

Basics on existence of skyrmions, based on https://doi.org/10.1098/rspa.2014.0394

The subrank and border subrank play central roles in several areas including algebraic complexity theory, quantum information theory, and combinatorics. In this talk, I will define subrank and border subrank of …

Graph learning is an active research domain in statistics, highlighted by well-known models such as Gaussian graphical models for i.i.d. data and autoregressive models for time series. In this talk, we will present …
