Book excerpt: Nous nous intéressons dans cette thèse à divers problèmes d'équations aux dérivées partielles elliptiques non-linéaires dans la première partie, nous construisons un contre-exemple pour montrer un résultat de non-existence de solutions d'ondes progressives pour un modèle intervenant en combustion dans un domaine cylindrique infini en dimension trois. L'objet de la deuxième partie est l'existence de solutions d'une équation semi-linéaire dans un cylindre fini, faisant intervenir le gradient dans le terme non-linéaire. Les conditions aux bords sont mixtes de type Dirichlet et Newmann. Nous utilisons la méthode de sous- et sur-solutions. La difficulté ici est le fait que le domaine possède des coins. Dans la troisième partie, nous étudions comme dans la première partie l'existence d'ondes progressives dans un domaine cylindrique infini dans le cas où le terme source change plusieurs fois de signe. Nous établissons une condition nécessaire et suffisante pour l'existence d'une onde. Enfin la quatrième partie a pour objet l'étude de la symétrie de solutions positives d'une équation aux dérivées partielles elliptique semi-linéaire dans des domaines sectoriels avec des conditions aux bords mixtes de Dirichlet et Newmann et utilise des développements récents sur la méthode de déplacement d'hyperplans

Book excerpt: First organized in 1981, the WASCOM conference to bring together researchers and scientists from all over the world to discuss problems, promote collaborations and shape future directions for research in the field of stability and wave propagation in continuous media.This book constitutes the proceedings of the 11th edition of the conference, the first of the third millennium. The main topics are: (1) Linear and nonlinear hyperbolic equations, conservation laws and specific aspects of wave propagation; (2) stability of systems of PDEs, with particular reference to those of fluid and solid mechanics; (3) extended thermodynamics and passage from microscopic to macroscopic description of the medium for systems characterized also by inelastic interactions at the kinetic scale.The proceedings have been selected for coverage in: ?

Book excerpt: Travelling wave processes and wave motion are of great importance in many areas of mechanics, and nonlinearity also plays a decisive role there. The basic mathematical models in this area involve nonlinear partial differential equations, and predictability of behaviour of wave phenomena is of great importance. Beside fluid dynamics and gas dynamics, which have long been the traditional nonlinear scienes, solid mechanics is now taking an ever increasing account of nonlinear effects. Apart from plasticity and fracture mechanics, nonlinear elastic waves have been shown to be of great importance in many areas, such as the study of impact, nondestructive testing and seismology. These lectures offer a thorough account of the fundamental theory of nonlinear deformation waves, and in the process offer an up to date account of the current state of research in the theory and practice of nonlinear waves in solids.

Available in PDF, EPUB and Kindle. Book excerpt: Ce cours d'analyse est consacré à l'exposition d'un certain nombre de thèmes classiques en théorie des équations aux dérivées partielles et s'adresse à des étudiants de master, des élèves en écoles d'ingénieurs ou à tous ceux qui désirent connaître cette partie importante des mathématiques. Ce travail part du théorème d'Existence et d'Unicité pour les solutions d'équations différentielles non-linéaires, aborde la résolution des équations scalaires linéaires du 1er ordre et s'intéresse ensuite aux équations scalaires quasi-linéaires. La transformation de Fourier ici présentée est très importante car elle permet de résoudre les équations à coefficients constants de la forme P(u) = F où P est un opérateur différentiel en (t, x). Les équations des ondes, de la chaleur et de Schrödinger sont toutes de ce type et font l'objet d'une résolution très détaillée au moyen de formules explicites. On quitte ensuite le domaine des équations à coefficients constants pour celui des équations à coefficients variables. Les méthodes employées pour résoudre ces équations donnent lieu à des développements très importants et font largement partie du domaine de la recherche.
