In 2013, Cattiaux and Guillin introduce the so-called HC(K) condition for $K \in \mathbb{R}$ on the drift and the diffusion coefficients of an $\mathbb{R}^d$-valued SDE to study the stability of the latter …

In this talk we consider the stationary nonlinear Schrodinger equation with radial bounded potentials. In the first part of the talk, we devise a procedure in order to prove the existence of two solutions through …

Étant donné un groupe libre F et K un corps, nous nous intéressons à l’anneau de groupe K[F]: il s’agit des fonctions de F dans K à support fini. L’anneau de groupe étant non commutatifs (sauf si F est isomorphe à …

The goal of this talk is to have a peak at the class field tower problem. For this, we will have to understand the concept involved. In the context of a number field (finite field extension of Q), I will give …

The Kähler–Ricci flow is a powerful parabolic tool for studying the geometry of Kähler manifolds. Its interplay with complex geometry suggests that singularity formation and continuation through singularities can be …

Abstract : Boolean functions (which transform a finite sequence of 0/1 bits, to a 0/1 value) are one of the basic objects of theoretical computer science. They arise in various areas of mathematics, as e.g. …
