Full textWir betrachten das zum 1-Laplace-Operator gehörige Eigenwertproblem. Wir definieren höhere Eigenlösungen mittels weak slope und weisen die Existenz einer Folge von Eigenlösungen nach, indem wir die nichtglatte Theorie kritischer Punkte anwenden. Zusätzlich leiten wir eine neue notwendige Bedingung für den ersten Eigenwert des 1-Laplace-Operators mittels innerer Variationen her

Full textfinite aquifers. Unsteady flow in the aquifer resulting from a constant discharge pumped from the stream is considered. Flow is one-dimensional, perpendicular to the stream in the confined aquifers. The stream is assumed to penetrate the full thickness of the aquifer. The aquifers may be semi-infinite or finite in width. The Laplace domain solutions are numerically inverted to the real-time domain with the Stehfest (1970) algorithm. During the course of the thesis a simple computer code is written to handle the algorithm and the code is verified by applying it to the one-dimensional transient flow in a semi-infinite homogeneous aquifer problem which can be solved analytically to crosscheck with the numerical results.

Full textThis thesis is divided in three distinct parts. The first one is concerned with variational problems involving the 1-Laplacian : an article is devoted to the best constants and extremals for the Sobolev trace map from W1,1(?) into L1(??), and a second work is about the first eigenvalue for the 1-Laplacian. The second part gives existence results for nonlinear PDEs of fourth order. The third part presents a method to prove the existence of a solution to problems involving the p-Laplacian with a Neuman condition on the boundary

Full textThis thesis deals with some singular and degenerated partial differential equations with constraint. We also consider some equations, called penalized equations, where the constraint is replaced with a term tending asymptotically towards the constraint. This allows us to obtain a more flexible numerical approximation of the initial partial differential equation with constraint. The first part of this thesis, which deals with the approximation of the first eigenvalue of the l-Laplacian operator, has been accepted for publication in the journal Annales de la Faculté des Sciences de Toulouse. Ln the second part, our results about the obstacle problem on Wa1,p, p» 1, generalize Adams and Lenhart's results obtained for the case p =2. Namely, we prave existence and uniqueness of a solution of the considered obstacle problem. The last part, which is the subject of a forthcoming paper, deals with an obstacle prablem on wa1, 1, which leads us to intraduce the space BV. The employed methods come from variational calculus, the theory of measured derivatives functions, vague topology, measure tight topology, convexity, duality theory, approximation and so on

Full textLa première partie de cette thèse a fait l'objet d'un article accepté pour publication aux Annales de la Faculté des Sciences de Toulouse.
Elle traite de l'approximation de la première valeur propre du 1-Laplacien.
Dans la deuxième partie, les résultats obtenus pour un problème d'obstacle sur $W_p^{0, 1}$, $p> 1$ généralisent le cas $p=2$, traité par Adams et Lenhart. On obtient donc l'existence et l'unicité d'une solution au problème posé.
La dernière partie qui fait l'objet d'un article en préparation, traite un problème d'obstacle sur $W_1^{0, 1}$, ce qui nécessite l'introduction de l'espace $BV$.
Les méthodes employées sont celles du calcul des variations, la théorie des fonctions à dérivées mesurées, la topologie vague, la topologie étroite des mesures, la convexité, la théorie de la dualité, l'approximation....

Full textIn the present PH.D. thesis we study three problems referred in the pseudo-Euclidean geometry. In the first two chapters, Chapter 1 and Chapter 2, we review known results and describe the basic notions of the Riemannian and Pseudo-Riemannian geometry. In Chapter 3, we study surfaces of revolution of the three dimensional Lorentz-Minkowski space satisfying given geometric condition. In Chapter 4, we find all the canonical forms of the shape operator of the three dimensional hypersurfaces of signature (-, +, -) of the four dimensional pseudo-Euclidean space of signature (-, +, -, +). Finally, in Chapter 5, we study the relation which exists between the biharmonic and minimal hypersurfaces referred in Chapter 4, by using their shape operator. Precisely, we prove that every such biharmonic hypersurface is minimal.
