Rational differential forms on line and singular vectors in Verma modules over
Vadim Schechtman, Alexander Varchenko
We construct a monomorphism of the De Rham complex of scalar multivalued meromorphic forms on the projective line, holomorphic on the complement to a finite set of points, to the c…
Asymptotic-preserving Particle-In-Cell methods for the Vlasov-Maxwell system near quasi-neutrality
Pierre Degond, Fabrice Deluzet, David Doyen
In this article, we design Asymptotic-Preserving Particle-In-Cell methods for the Vlasov-Maxwell system in the quasi-neutral limit, this limit being characterized by a Debye length…
A continuum model for nematic alignment of self-propelled particles
Pierre Degond, Angelika Manhart, Hui Yu
A continuum model for a population of self-propelled particles interacting through nematic alignment is derived from an individual-based model. The methodology consists of introduc…
An adaptive kriging method for solving nonlinear inverse statistical problems
Shuai Fu, Mathieu Couplet, Nicolas Bousquet
In various industrial contexts, estimating the distribution of unobserved random vectors Xi from some noisy indirect observations H(Xi) + Ui is required. If the relation between Xi…
Sharp estimates for discrete second order {R}iesz transforms
Komla Domelevo, Stefanie Petermichl
We show that multipliers of second order Riesz transforms on products of discrete abelian groups enjoy the estimate , where and $p…
Non-convex Regularizations for Feature Selection in Ranking With Sparse SVM
Léa Laporte, Rémi Flamary, Stephane Canu +2
Feature selection in learning to rank has recently emerged as a crucial issue. Whereas several preprocessing approaches have been proposed, only a few works have been focused on in…
The Einstein-Hilbert functional and the Sasaki-Futaki invariant
Charles P. Boyer, Hongnian Huang, Eveline Legendre +1
We show that the Einstein-Hilbert functional, as a functional on the space of Reeb vector fields, detects the vanishing Sasaki-Futaki invariant. In particular, this provides an obs…
Multi-speed solitary waves of nonlinear Schr{ö}dinger systems: theoretical and numerical analysis
Fanny Delebecque, Stefan Le Coz, Rada-Maria Weishäupl
We consider a system of coupled nonlinear Schr{ö}dinger equations in one space dimension. First, we prove the existence of multi-speed solitary waves, i.e solutions to the system w…
Continuum model for linked fibers with alignment interactions
Pierre Degond, Fanny Delebecque, Diane Peurichard
We introduce an individual-based model for fiber elements having the ability to cross-link or unlink each other and to align with each other at the cross links. We first formally d…
Compressed sensing with structured sparsity and structured acquisition
Claire Boyer, Jérémie Bigot, Pierre Weiss
Compressed Sensing (CS) is an appealing framework for applications such as Magnetic Resonance Imaging (MRI). However, up-to-date, the sensing schemes suggested by CS theories are m…
Large time behavior for a quasilinear diffusion equation with critical gradient absorption
Razvan Gabriel Iagar, Philippe Laurençot
We study the large time behavior of non-negative solutions to the nonlinear diffusion equation with critical gradient absorption $$\partial\_t u - Δ\_{p}u + |\nabla u|^{q\_*} = 0 \…
Some superconcentration inequalities for extrema of stationary Gaussian Processes
Kevin Tanguy
This note is concerned with concentration inequalities for extrema of stationary Gaussian processes. It provides non-asymptotic tail inequalities which fully reflect the fluctuatio…
Mathematical Modelling, Simulation, and Optimal Control of the 2014 Ebola Outbreak in West Africa
Amira Rachah, Delfim F. M. Torres
The Ebola virus is currently one of the most virulent pathogens for humans. The latest major outbreak occurred in Guinea, Sierra Leonne and Liberia in 2014. With the aim of underst…
Regret bounds for Narendra-Shapiro bandit algorithms
Sébastien Gadat, Fabien Panloup, Sofiane Saadane
Narendra-Shapiro (NS) algorithms are bandit-type algorithms that have been introduced in the sixties (with a view to applications in Psychology or learning automata), whose converg…
