This book describes a family of algorithms for studying the global structure of systems. By a finite covering of the phase space we construct a directed graph with vertices corresponding to cells of the covering and edges corresponding to admissible transitions. The method is used, among other things, to locate the periodic orbits and the chain recurrent set, to construct the attractors and their basins, to estimate the entropy, and more.

Les methodes spectrales sont une technique recente d'approximation de la solution d'equations aux derivees partielles par des polynomes de haut degre. Elles ont un degre de precision infini: l'ordre de l'erreur ne depend que de la solution a approcher. Leur utilisation s'est enormement developpee ces dernieres annees.

Le sujet de ce livre est l'analyse numerique des methodes spectrales. Il presente de facon unifiee les notions de base, parmi lesquelles certains resultats recents, et donne quelques applications (en particulier la discretisation du probleme de Stokes). Une attention...

Graduate students and postgraduates in Mathematics, Engineering and the Natural Sciences want to understand Applied Mathematics for the solution of everyday problems. Scholars of Roland Bulirsch working at universities, at research institutions and in industry combine research and review papers in this anthology. Their work is summed up under the title "From Nano to Space Applied Mathematics Inspired by Roland Bulirsch." More than 20 contributions are divided into scales: nano, micro, macro, space and real life. The contributions survey current research and present case studies very...

This book features articles written by some of the most prominent leading applied mathematicians as well as young and promising ones. The common objective of these articles is to present an important issue which is currently widely discussed in scientific investigation with major human, economic or ecological implications. Each article is as deep as an expert lecture but is also self-contained, so that even isolated scientists with limited resources can profit greatly from it.

The general goal of this book is to deduce rigorously, from the first principles, the partial differential equations governing the thermodynamic processes undergone by continuum media under forces and heat. Solids and fluids are considered in a unified framework. Reacting mixtures of fluids are also included for which general notions of thermodynamics are recalled, such as the Gibbs equilibrium theory.

Linear approximate models are mathematically obtained by calculating the derivatives of the constitutive response functions. They include the classical models for linear vibrations of...

Ce livre est une introduction a la theorie de la complexite algebrique basee sur un panorama des methodes algorithmiques en algebre lineaire exacte. Il donne en particulier les principaux algorithmes pour le calcul du polynome caracteristique. Ce livre se remarque par l'etendue des sujets traites tout en restant tres lisible."

L'ouvrage presente la technique de simulation des grandes echelles. Les bases mathematiques et les hypotheses physiques employees sont rappelees. Les concepts de modelisation structurelle et de modelisation fonctionnelle sont introduits, et servent a etablir une liste exhaustive, unique a ce jour, des modeles sous-maille existants. Outre la description de ces modeles, le lecteur trouvera des elements theoriques et des details pratiques concernant leur mise en oeuvre.

This volume includes four lecture courses by Bressan, Serre, Zumbrun and Williams and a Tutorial by Bressan on the Center Manifold Theorem. Bressan introduces the vanishing viscosity approach and clearly explains the building blocks of the theory. Serre focuses on existence and stability for discrete shock profiles. The lectures by Williams and Zumbrun deal with the stability of multidimensional fronts.
