Abstract
In these notes we present some recent results on the development
of hybrid methods for hyperbolic and kinetic equations with
multiple scales. The main ingredients in the schemes are a
suitable merging of particle methods in non stiff regimes with
high resolution shock capturing techniques in stiff ones. The key
aspect in the development of the algorithms is the choice of a
suitable hybrid representation of the solution.
Résumé
Nous présentons dans ces notes quelques résultats récents concernant le développement de méthodes hybrides
pour les équations hyperboliques et cinétiques. L'ingrédient principal de ces schémas
réside dans un mélange pertinent
de méthodes particulaires dans les régimes réguliers
et de techniques haute résolution de capture de choc dans les zones raides.
La clef du développement de ces algorithmes est donnée par le choix d'une bonne représentation hybride de la solution.
Key words: multiscale problems, particle methods, high-resolution schemes, hyperbolic conservation laws, stiff terms, kinetic equations

| What is OpenURL? |
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
