Soit X un objet géométrique (variété complexe, algébrique, symplecique,...). Un problème énumératif consiste à compter les sous-objets satisfaisant des contraintes fixées. Une idée naturelle consiste à dégénérer X, …

In this talk, we will give an overview of some topics in Valuation Theory and explore the valuative tree. We will write a parametrization of the space of valuations over a polynomial ring K[x] using pseudo-Cauchy …

Complex symplectic structures arise naturally in hyperkähler geometry, and in complex algebraic geometry the terms “complex symplectic” and “hyperkähler” are often used interchangeably, since the two notions are …

Paper

We study the three dimensional cubic defocusing wave equation with Gaussian initial data. We show that the law of the solution is quasi-Gaussian in low regularity regimes exploiting renormalised energies, normal …

During this presentation, I will introduce the concept of minimization problems in an abstract setting, as well as some classical topological tools for addressing them: a basic acquaintance with lower semicontinuity …

Lorsque $\omega$ est une racine primitive $n$-ième de l'unité, le polynôme quadratique $F(z)=\omega z(1-z)$ a un point fixe parabolique en $0$. Sa multiplicité parabolique est égale à $1$, c'est-à-dire que …
