This book was released on 2006 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse traite différents sujets de la théorie des équations aux dérivées partielles elliptiques et paraboliques. La partie centrale est dédiée à l'étude de la validité de théorèmes de type Liouville pour opérateurs elliptiques linéaires, semi linéaires et complètement non linéaires. Avec "théorèmes de type Liouville" on entend l'unicité (multiplication par une constante près dans le cas des équations linéaires) des solutions bornées (parfois positives) d'une équation elliptique dans un domaine non borné, en analogie avec le théorème classique pour fonctions harmoniques. Nous avons montré que le théorème de type Liouville est valable pour les opérateurs linéaires à coefficients périodiques dans tout l'espace et il n'est plus valable en générale si les coefficients sont seulement presque périodiques.Pour démontrer des théorèmes de Liouville pour des équations semi linéaires on a du introduire des notions qui généralisent celle de la valeur propre principale. Les définitions et l'étude des propriétés de ces valeurs propres principales généralisées font l'objet de la première partie de la thèse, qui est la plus abstraite. La partie regardante les équations elliptiques est conclue par des résultats d'unicité de solutions de viscosité non négatives pour une classe d'équations complètement non linéaires. Le dernier sujet traité dans la thèse est celui des équations de réaction diffusion et, en particulier, de l'étude du comportement des solutions à long terme. L'un des résultats présentés regarde des équations avec vitesse forcée, qui interviennent dans plusieurs modèles de mathématiques appliquées, notamment en écologie.

Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de ce travail est d'établir l'existence et l'unicité de la solution pour une équation elliptique non linéaire dégénérée, posée dans un domaine non borné. Dans un premier temps, on mène notre étude dans un domaine borné et ceci en tronquant le domaine infini. Dans la première partie, on introduit le problème variationnel associé qui se traduit en terme d'une fonctionnelle non coercive à minimiser. Ainsi, on associe au problème de minimisation un problème dual puis on montre pour ce dernier l'existence et l'unicité de la solution. On prouve par l'extraction d'une sous-suite minimisante l'existence d'une solution liée à celle du pro-blème dual. Dans la deuxième partie, on définit un problème relaxé ayant le même infimum que le problème initial et on prouve l'existence d'une solution pour le problème relaxé. Les résultats de la première partie sont étendus au cas non borné. Enfin on estime l'erreur de tron-cature entre les solutions du problème dual dans le cas borné et non borné.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents advanced methods of integral calculus and optimization, the classical theory of ordinary and partial differential equations and systems of dynamical equations. It provides explicit solutions of linear and nonlinear differential equations, and implicit solutions with discrete approximations.The main changes of this second edition are: the addition of theoretical sections proving the existence and the unicity of the solutions for linear differential equations on real and complex spaces and for nonlinear differential equations defined by locally Lipschitz functions of the derivatives, as well as the approximations of nonlinear parabolic, elliptic, and hyperbolic equations with locally differentiable operators which allow to prove the existence of their solutions; furthermore, the behavior of the solutions of differential equations under small perturbations of the initial condition or of the differential operators is studied.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage est issu d’un cours de Master 2 enseigné à l’UPMC entre 2004 et 2007. Nous y présentons une sélection de techniques mathématiques orientées vers la résolution des équations aux dérivées partielles elliptiques semi-linéaires et quasi-linéaires. Après un vade-mecum d'analyse réelle et d'analyse fonctionnelle de base pour les EDP, sans démonstrations pour les points les plus connus, nous parcourons ainsi les théorèmes de point fixe classiques, les opérateurs de superposition dans les espaces de Lebesgue et de Sobolev, la méthode de Galerkin, les principes du maximum et la régularité elliptique, nous faisons une excursion assez longue dans divers aspects du calcul des variations puis terminons par les opérateurs monotones et pseudo-monotones. Tout ceci est agrémenté d’exemples et chaque chapitre est complété d'un nombre d’exercices qui croît essentiellement avec le numéro du chapitre, au fur et à mesure que de nouveaux matériaux sont présentés. This book stems from lectures notes of a Master 2 class held at UPMC between 2004 and 2007. A selection of mathematical techniques geared towards the resolution of semilinear and quasilinear elliptic partial differential equations is presented. After a short survival guide in basic real and functional analysis for PDEs, without proofs for the most well-known results, we walk through the classical fixed point theorems, the superposition operators in Lebesgue and Sobolev spaces, the Galerkin method, the maximum principles and elliptic regularity, we make a rather long foray into various aspects of the calculus of variations, and conclude with monotone and pseudo-monotone operators, by way of numerous examples. Each chapter is complemented by a number of exercises that grows with the chapter number as more and more material is made available.
