Error estimate for the Finite Volume Scheme applied to the advection equation
Benoit Merlet, Julien Vovelle
We study the convergence of a Finite Volume scheme for the linear advection equation with a Lipschitz divergence-free speed in . We prove a -error estimate in the $L…
Asymptotics of a thermal flow with highly conductive and radiant suspensions
F. Benthala, I. Gruais, D. Polisevski
Radiant spherical suspensions have an $\veps$-periodic distribution in a tridimensional incompressible viscous fluid governed by the Stokes-Boussinesq system. We perform the homoge…
On the non additivity of the trace in derived categories
Daniel Ferrand
In this note we provide an example of an endomorphism of a short exact sequence of perfect complexes, with the trace of the middle map not equal to the sum of the traces of the two…
Homogenization of a diffusion process in a rarefied binary structure
Fadila Bentalha, Isabelle Gruais, Dan Polisevski
We study the homogenization of a diffusion process which takes place in a binary structure formed by an ambiental connected phase surrounding a suspension of very small spheres dis…
Constructions in public-key cryptography over matrix groups
Dimitri Grigoriev, Ilia Ponomarenko
The purpose of the paper is to give new key agreement protocols (a multi-party extension of the protocol due to Anshel-Anshel-Goldfeld and a generalization of the Diffie-Hellman pr…
Feuilletages en droites, équations des eikonales et aures équations différentielles
Dominique Cerveau
We study complex vector fields with straight lines trajectories. Some applications to rational solutions of ikonals equations are given
