This presentation is divided into two parts. First talk: Cluster structures for type E_n homogeneous varieties Abstract: We will present a gentle overview of cluster algebras of geometric type, and introduce one of their generalisations due to Lam and Pylyavskyy.
Reinterpreting finite sets as vector spaces over F1 (the nonexistent field with one element) yields a combinatorial degeneration of linear algebra. Representation theory over these new vector spaces turns out to be closely related to graph theory. We will introduce
Keyed-verification anonymous credentials are widely recognized as some of the most efficient tools for anonymous authentication. In this work, we revisit two prominent credential systems: the scheme by Chase et al. (CCS 2014), commonly referred to as CMZ or PS
Résumé: La dépolymérisation (c'est-à-dire le raccourcissement progressif) de grosses molécules peut être modélisée par des équations discrètes, de type Becker-Döring, ou par des équations continues. Dans de nombreuses applications, la nature dynamique des expériences, ainsi que leur échelle nanométrique, rend
Résumé : This talk is devoted to a statistical approach to nonlinear waves on surfaces. Specifically, we consider the cubic Schrödinger equation (NLS) posed on the 2 dimensional sphere and we study the collective dynamics of initial data distributed according
Abstract: Over the last decades, the well-posedness issue of stochastic dispersive PDEs with multiplicative noises has been extensively studied. However, this study was done primarily from the viewpoint of Ito solution theory, and pathwise well-posedness remained completely open. In this
Résumé : La théorie du contrôle consiste à se poser la question : si on peut agir sur un système, que peut-on lui faire faire ? L'une des principales problématiques est le problème de stabilisation : comment agir sur un système en fonction
