In this article we are interested in the regularization of divergent traces. The notion of trace plays a fundamental role in non-commutative geometry. The trace can be interpreted as an "operator" that replaces the integration in classical analysis.

The aim of this thesis is to develop a statistical approach to learn the dependence structure of extremes in a high-dimensional setting. The first chapter brings together the main results concerning multivariate extreme value theory. The different to

Studying the dependence of extreme events has so far only been dealt in low dimension. The aim of this thesis is to develop a statistical approach to learn the dependence structure of extremes in a high-dimensional setting. The first chapter brings t

The present thesis is devoted to the study of the effect of a perturbation on the spectrum of a Hermitian matrix by a random matrix with small operator norm and whose entries in the eigenvector basis of the first one were independent, centered and wi

Dans cet article, on introduit la notion de série Dirichlet associée aux zéros d'une fonction analytique. En utilisant les critères de majoration du nombre de zéros comptés avec leur ordre de multiplicité, on démontre que la fonction zêta es

Cette thèse porte sur l'étude de la modélisation et estimation de la dépendance des portefeuilles de risques et l'estimation du risque agrégé. Dans le Chapitre 2, nous proposons une nouvelle méthode pour estimer les quantiles de haut niveau po

This thesis comprises three essays on estimation methods for the dependence between risks and its aggregation. In the first essay we propose a new method to estimate high level quantiles of sums of risks. It is based on the estimation of the ratio be

We establish a large deviation principle for the empirical spectral measure of a sample covariance matrix with sub-Gaussian entries, which extends Bordenave and Caputo's result for Wigner matrices having the same type of entries [7]. To this aim, we

My PhD work is composed of two parts, the first part is dedicated to the discrete-time stochastic analysis for obtuse random walks as to the second part, it is linked to free probability. In the first part, we present a construction of the stochastic
