There are many results on the statistical properties of the root locus of various families of polynomials. Examples are: Brolin’s theorem for the family of iterates of any fixed polynomial of degree at least $2$. …

Description : La formation s’adresse à des personnes qui ont un niveau initié et veulent approfondir leurs connaissances en statistique. Elle est orientée vers la compréhension des bases de la modélisation par …

I will present an overview of the results and methods on the estimation of Poisson, Newton and transition(heat) kernels for Dyson Brownian Motions and the stochastic diffusion processes of Dunkl and Opdam-Cherednik. …

In this talk, I'll present a few interdisciplinary research projects I'm involved in. They take place in two main domains: biology and sports. For the biology, I'll present the mixOmics R package. It's dedicated to …

The space of (local) symmetries of a given geometric structure has the natural structure of a Lie (pseudo)group. Conversely, geometric structures admitting a local model can be described via the pseudogroup of …

We study a two-component coagulation equation that models the aggregation of rouleaux in blood. We consider product kernels that have homogeneity 2 and we characterize the initial data that lead to gelation. We …

Le théorème de formalité de Kontsevich explique comment passer d’une structure de Poisson à un star-produit, c’est-à-dire à une déformation associative du produit des fonctions. Je rappellerai d’abord d’où vient …

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 …
