Best constants in Lieb-Thirring inequalities: a numerical investigation
We investigate numerically the optimal constants in Lieb-Thirring inequalities by studying the associated maximization problem. We use a monotonic fixed-point... -
Opinion groups formation and dynamics : structures that last from non lasting...
We extend simple opinion models to obtain stable but continuously evolving communities. Our scope is to meet a challenge raised by sociologists of generating... -
Double extensions of Lie algebras of Kac-Moody type and applications to some ...
We shall describe some Lie algebras of Kac-Moody type, construct their double extensions, central and by derivations; in some cases, the corresponding Lie groups will... -

Quick Summary is an innovate implementation of an automatic document summarizer that inputs a document in the English language and evaluates each sentence. The scanner... -
André Masson. Une résistance d'exil (1938-1947)
Dans la période considérée pour l'exposition de l'automne 2012 au MAMVP, l'oeuvre de Masson est traversée par une inspiration mythique, du "Labyrinthe" (1938) à... -
Spectral learning of graphical distributions
This work draws on previous works regarding spectral learning algorithm for structured data (see \cite{Hsu:COLT09-long}, \cite{DBLP:conf/icml/SongSGS10},... -
Le Vierge, le vivace et le bel aujourd'hui : trois mouvements de la structure...
Nous considérons l'incidence sur la notion d'espace sous-jacent de trois types de dynamiques : la théorie KAM, la dynamique donnée par des potentiels peu réguliers et... -
On a conjecture by Pierre Cartier about a group of associators.
In \cite{cartier2}, Pierre Cartier conjectured that for any non commutative formal power series $\Phi$ on $X=\{x_0,x_1\}$ with coefficients in a $\Q$-extension, $A$,... -
Positivity cases, estimates and asymptotic expansions for condenser capacities
We study positivity cases, estimates and asymptotic expansions of condenser p-capacities of points and segments in a bounded domain, having in mind application fields,... -

Hitting properties and non-uniqueness for SDE driven by stable processes
We study a class of self-similar jump type SDEs driven by Hölder-continuous drift and noise coefficients. Using the Lamperti transformation for positive self-similar... -
Longtime Behavior for Mutually Catalytic Branching with Negative Correlations
In several examples, dualities for interacting diffusion and particle systems permit the study of the longtime behavior of solutions. A particularly difficult model in... -
Mutually Catalytic Branching Processes on the Lattice and Voter Processes wit...
Since the seminal work of Dawson and Perkins, mutually catalytic versions of super-processes have been studied frequently. In this article we combine two approaches... -
Etat de l'art : Le temps dans les entrepôts de documents XML
Les documents électroniques (rapports, notes, articles...) évoluent et présentent des contenus de plus en plus riches et complexes. Ainsi, ils font l'objet de... -
Large deviations for the empirical measure of Markov renewal processes
A large deviations principle is established for the joint law of the empirical measure and the flow measure of a renewal Markov process on a finite graph. We do not...
