On se place sur le tore (discret) de côté n et de dimension d. Imaginons qu’un pyromane allume des départs de feu alors que pendant ce temps, le feu se propage le long des arêtes. Au bout de combien de temps le tore …

Many aspects of two-dimensional conformal field theory (even though not all) can be approached by the means of topological techniques as demonstrated for instance by the construction of correlators in rational …

We will first review previous work on explainable AI methods and present two works on this topic. We will first present Opti-CAM, a CAM-based method that optimizes a masking objective per instance. The resulting …

In recent years, strata of Abelian differentials have become central objects of study in Algebraic Geometry. Their rich structure can be approached from several perspectives, including combinatorics, Teichmüller …

In discrete geometry, we study configurations of points under certain conditions. We are mostly interested in extremal configurations: What is the densest packing of spheres in R^n? What is the minimum number of …

 Le système de numération en base rationnelle p/q a été introduit en 2008 par Akiyama, Frougny et Sakarovitch. Pour deux entiers p>q copremiers, tout entier n possède une unique expansion en base p/q, sous la …
