Non-ergodicity of Nose-Hoover dynamics
Frederic Legoll, Mitchell Luskin, Richard Moeckel
The numerical integration of the Nose-Hoover dynamics gives a deterministic method that is used to sample the canonical Gibbs measure. The Nose-Hoover dynamics extends the physical…
A unified approach to Mimetic Finite Difference, Hybrid Finite Volume and Mixed Finite Volume methods
Jerome Droniou, Robert Eymard, Thierry Gallouët +1
We investigate the connections between several recent methods for the discretization of anisotropic heterogeneous diffusion operators on general grids. We prove that the Mimetic Fi…
Asymptotics of one-dimensional forest fire processes
Xavier Bressaud, Nicolas Fournier
We consider the so-called one-dimensional forest fire process. At each site of , a tree appears at rate . At each site of , a fire starts at rate ,…
Hyperdeterminantal computation for the Laughlin wave function
Adrien Boussicault, Jean-Gabriel Luque, Christophe Tollu
The decomposition of the Laughlin wave function in the Slater orthogonal basis appears in the discussion on the second-quantized form of the Laughlin states and is straightforwardl…
Mass conservative BDF-discontinuous Galerkin/explicit finite volume schemes for coupling subsurface and overland flows
Pierre Sochala, Alexandre Ern, Serge Piperno
Robust and accurate schemes are designed to simulate the coupling between subsurface and overland flows. The coupling conditions at the interface enforce the continuity of both the…
Adiabatic approximation, Gell-Mann and Low theorem and degeneracies: A pedagogical example
Christian Brouder, Gabriel Stoltz, Gianluca Panati
We study a simple system described by a 2x2 Hamiltonian and the evolution of the quantum states under the influence of a perturbation. More precisely, when the initial Hamiltonian…
A Proximal Decomposition Method for Solving Convex Variational Inverse Problems
Patrick L. Combettes, Jean-Christophe Pesquet
A broad range of inverse problems can be abstracted into the problem of minimizing the sum of several convex functions in a Hilbert space. We propose a proximal decomposition algor…
Global well-posedness issues for the inviscid Boussinesq system with Yudovich's type data
R. Danchin, M. Paicu
The present paper is dedicated to the study of the global existence for the inviscid two-dimensional Boussinesq system. We focus on finite energy data with bounded vorticity and we…
Free quasi-symmetric functions and descent algebras for wreath products, and noncommutative multi-symmetric functions
Jean-Christophe Novelli, Jean-Yves Thibon
We introduce analogs of the Hopf algebra of Free quasi-symmetric functions with bases labelled by colored permutations. When the color set is a semigroup, an internal product can b…
The Dirichlet problem for the minimal surface equation -with possible infinite boundary data- over domains in a Riemannian surface
L. Mazet, M. M. Rodriguez, H. Rosenberg
In this paper, we study existence and uniqueness of solutions to Jenkins-Serrin type problems on domains in a Riemannian surface. In the case of unbounded domains, the study is foc…
A collocated finite volume scheme to solve free convection for general non-conforming grids
Eric Chénier, Robert Eymard, Raphaele Herbin
We present a new collocated numerical scheme for the approximation of the Navier-Stokes and energy equations under the Boussinesq assumption for general grids, using the velocity-p…
A characterization of dimension free concentration in terms of transportation inequalities
Nathael Gozlan
The aim of this paper is to show that a probability measure concentrates independently of the dimension like a gaussian measure if and only if it verifies Talagrand's $\T_2$ transp…
A Note about proving non- under a finite non-microstates free Fisher information Assumption
Yoann Dabrowski
We prove that if are selfadjoints in a -probability space with finite non-microstates free Fisher information, then the von Neumann algebra $W^{*}(X…
Continuous crystals and Duistermaat-Heckman measure for Coxeter groups
Philippe Biane, Philippe Bougerol, Neil O'Connell
We introduce a notion of continuous crystal analogous, for general Coxeter groups, to the combinatorial crystals introduced by Kashiwara in representation theory of Lie algebras. W…
Statistical analysis of self-similar conservative fragmentation chains
Marc Hoffmann, Nathalie Krell
We explore statistical inference in self-similar conservative fragmentation chains when only approximate observations of the sizes of the fragments below a given threshold are avai…
An Application of the Feferman-Vaught Theorem to Automata and Logics for<br> Words over an Infinite Alphabet
Alexis Bès
We show that a special case of the Feferman-Vaught composition theorem gives rise to a natural notion of automata for finite words over an infinite alphabet, with good closure and…
Curvature in conformal mappings of 2D lattices and foam structure
A. Mughal, D. Weaire
The elegant properties of conformal mappings, when applied to two dimensional (2D) lattices, find interesting applications in 2D foams and other cellular or close packed structures…
