Book excerpt: IL EST CONNU Q'UNE SOLUTION CONTINUE DU PROBLEME DE CAUCHY RELATIF A UN SYSTEME NON LINEAIRE N'EXISTE QUE DANS UN VOISINAGE DES DONNEES INITIALES, NOUS NOUS PROPOSONS D'OBSERVER L'EXPLOSION DE LA SOLUTION EN FONCTION DE DONNEES REGULIERES A SUPPORT COMPACT. ON CONSIDERE UN SYSTEME HYPERBOLIQUE NON LINEAIRE DU PREMIER ORDRE D'EQUATIONS AUX DERIVEES PARTIELLES. LA THESE SE COMPOSE DE DEUX PARTIES. DANS LA PREMIERE PARTIE, NOUS RAPPELONS LE CAS D'UNE VARIABLE SPACIALE, RESOLU ANALYTIQUEMENT, LORSQUE LE SYSTEME SE REDUIT A UNE EQUATION A UNE INCONNUE, A UN SYSTEME DE DEUX EQUATIONS A DEUX INCONNUES, PUIS A UN SYSTEME DE K EQUATIONS A K INCONNUES, ET OBSERVONS L'EXPLOSION DE LA SOLUTION EN RAISON INVERSE DE L'AMPLITUDE DES DONNEES INITIALES SI LE SYSTEME EST STRICTEMENT HYPERBOLIQUE ET VERITABLEMENT NON LINEAIRE. DANS LA DEUXIEME PARTIE, NOUS TRAITONS LE CAS DE N VARIABLES SPACIALES DONT LA RESOLUTION ANALYTIQUE PARAIT PLUS DIFFICILE. POUR CE FAIT, NOUS CONSTRUISONS UN DEVELOPPEMENT ASYMPTOTIQUE FORMEL DE LA SOLUTION AU VOISINAGE D'UNE SOLUTION DONNEE. LES TERMES DU DEVELOPPEMENT, RAPPORTES A UNE BASE DE VECTEURS PROPRES DE LA MATRICE CARACTERISTIQUE, SONT DETERMINES AU MOYEN D'EQUATIONS DIFFERENTIELLES ORDINAIRES LE LONG DES BICARACTERISTIQUES DU SYSTEME. NOUS REMARQUONS ALORS L'EXPLOSION DU PREMIER TERME ET PAR CONSEQUENT DE LA SOLUTION EN RAISON INVERSE DE L'AMPLITUDE DES DONNEES INITIALES, LORSQUE LE SYSTEME EST STRICTEMENT HYPERBOLIQUE ET VERITABLEMENT NON LINEAIRE DANS LE SENS ADMIS GENERALEMENT

Download or read book Nonlinear Differential Equations written by Piero de Mottoni and published by Academic Press. This book was released on 2014-05-10 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear Differential Equations: Invariance, Stability, and Bifurcation presents the developments in the qualitative theory of nonlinear differential equations. This book discusses the exchange of mathematical ideas in stability and bifurcation theory. Organized into 26 chapters, this book begins with an overview of the initial value problem for a nonlinear wave equation. This text then focuses on the interplay between stability exchange for a stationary solution and the appearance of bifurcating periodic orbits. Other chapters consider the development of methods for ascertaining stability and boundedness and explore the development of bifurcation and stability analysis in nonlinear models of applied sciences. This book discusses as well nonlinear hyperbolic equations in further contributions, featuring stability properties of periodic and almost periodic solutions. The reader is also introduced to the stability problem of the equilibrium of a chemical network. The final chapter deals with suitable spaces for studying functional equations. This book is a valuable resource for mathematicians.

This book was released on 2013-01-21 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Qu’il s’agisse d’applications en physique ou en mécanique, en médecine ou en biologie, mais aussi en économie, dans les médias et en marketing, ou encore dans le domaine des finances, la traduction phénoménologique du système étudié conduit très souvent à la résolution d’équations différentielles ou aux dérivées partielles. Incontestablement, ce sont les éléments finis qui ont bouleversé le monde de l’approximation numérique des équations aux dérivées partielles. Cet ouvrage est composé de deux parties : la première est un abrégé de cours portant sur les outils de base de l’analyse mathématique des équations aux dérivées partielles et la seconde contient des problèmes corrigés qui abordent l’approximation par éléments finis des formulations variationnelles des problèmes aux limites elliptiques. Des applications en mécanique des solides déformables, à la résistance des matériaux, en mécanique des fluides et en thermique ainsi que quelques problèmes non linéaires y sont présentés.Cet ouvrage s'adresse aux étudiants en sciences et techniques de l'ingénieur des universités et des grandes écoles.

Download or read book Dynamical Systems written by A. R. Bednarek and published by Academic Press. This book was released on 2014-06-28 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamical Systems compiles the lectures and contributed papers read at the International Symposium on Dynamical Systems held at the University of Florida in Gainesville, Florida on March 24-26, 1976. This book discusses the principle of exchange of stability; weak-invariance and rest points in control systems; local controllability in nonlinear systems; and unitary treatment of various types of systems in stability-theory. The optimization of structural geometry; dispersal manifolds in partial differential games; remarks on existence theorems for Pareto optimality; and stability of solutions bifurcating from steady or periodic solutions are also elaborated. This compilation likewise covers the linear neutral functional differential equations on a Banach space; radiation reaction in electrodynamics; and buckling of cylindrical shells with small curvature. This publication is beneficial to students and researchers working on dynamical systems.

Available in PDF, EPUB and Kindle. Book excerpt: On étudie des systèmes d'équations aux dérivées partielles non linéaires fortement couplées. Pour montrer l'existence locale, l'unicité et la régularité de la solution ainsi que son existence globale dans le cas a 1 dimension, on est amené à combiner les techniques paraboliques classiques et les techniques hyperboliques. Ces systèmes s'obtiennent en perturbant par viscosité: en ajoutant des termes de diffusion a des systèmes hyperboliques non linéaires. On étudie la convergence de la méthode de viscosité, c'est-a-dire de la convergence, quand les coefficients de diffusion tendent vers 0, de la solution de systèmes ainsi perturbes vers la solution du système hyperbolique associé.
