Dans cet exposé, je discuterai de l’auto-adjonction de l’opérateur de Dirac en 2D couplé avec une combinaison d’interactions $\delta$ du type électrostatiques et scalaires de Lorentz, supportée sur une courbe fermée …

Description : Le package data.table s’avère très efficace pour la manipulation de données, en temps et mémoire. Il permet en particulier de traiter avec R d’importants volumes de données. Pour plus …

Microwave imaging defines an inverse problem that is severely ill-posed but with interesting potential applications. In this talk, we will first talk about the direct problem, involving Maxwell's equations, and then …

Modular functors are families of finite-dimensional representations of Mapping Class Groups of surfaces, with strong compatibility conditions. As Mapping Class Groups of surfaces are isomorphic to fundamental groups …

The Higman-Thompson groups are groups of certain self-homeomorphisms of Cantor sets. They can be described using tree diagrams. We compute their homology in a stable range by constructing a scanning map following …

The Pythagoras number of a field is defined as the smallest positive integer n such that each sum of squares in the field is a sum of n squares. For example, the Pythagoras number of the field of rational numbers Q …

In this presentation, we will discuss recursive towers of curves over finite fields. Before defining this object, we will first highlight their relevance through a concrete application: error-correcting codes. We …

Motivated by various problems in complex geometry, including Siu's conjecture on the invariance of the plurigenera in Kähler families of compact complex manifolds, we give an L^2 extension theorem, from a complex …
