The goal of this article is to give a new proof of the wave trace formula proved by Richard Melrose in an impressive article. This trace formula is an extension of the Chazarain-Duistermaat-Guillemin trace formula (denoted as “CDG trace formula”

International audience; We establish small-time asymptotic expansions for heat kernels of hypoelliptic Hörmander operators in a neighborhood of the diagonal, generalizing former results obtained in particular by Métivier and by Ben Arous. The coeff

L'ouvrage a pour objectif de donner une vision assez large des manifestations et approches de la turbulence et conduit le lecteur à s'interroger de lui-même sur le déterminisme. La découverte de thèmes aujourd'hui incontournables en sciences.

We prove that for the Martinet wave equation with "flat" metric, which a subelliptic wave equation, singularities can propagate at any speed between 0 and 1 along any singular geodesic. This is in strong contrast with the usual propagation of singula

The density stratification in an incompressible fluid is responsible for the propagation of internal waves. In domains with topography, these waves exhibit interesting features. In particular, numerical and lab experiments show that, in two dimension

International audience; We extend the results of our paper "Attractors for two dimensional waves with homogeneous Hamiltonians of degree 0"written with Laure Saint-Raymond to the case of forced linear wave equations in any dimension. We prove that, i

In this paper, we describe the weak limits of the measures associated to the eigenfunctions of the Laplacian on a Quantum graph for a generic metric in terms of the Gauss map of the determinant manifold. We describe also all the limits with minimal s

International audience; In this note, we present a natural proof of a recent and surprising result of Gregory Berkolaiko (arXiv 1110.5373) interpreting the "Courant nodal defect" of a Schrödinger operator on a finite graph as a Morse index associate
