Full textThis thesis deals with the Backward stochastic differential equations (BSDEs for short) and their applications. The first part is devoted to the double barrier refiected BSDEs. We show the existence of a solution for su ch equations when the barriers are completely separate and the generator is continuous with quadratic growth. As an application we solve the risk-sensitive mixed zero-sum stochastic differential game. Ln addition we deal with recallable options under K nightian uncertainty. Ln the second part, we focus on a real option problem namely the starting and stopping problem when the noise is driven by a Brownian motion and an independent Poisson process. This problem is tackled in using the notion of Snell envelope and BSDEs with jumps. We de rive a stochastic verification theorem which we show later that is satisfied. LVhen the random noise stems from a standard SDE with jumps we show that the problem is related to a system of two variational inequalities, hence we give a deterministic verification result. Finally, we deal with the problem with exponential utilities

Full textNotre recherche s'inscrit dans la continuité des travaux de recherche de Durand-Guerrier et nous soutenons la thèse selon laquelle la logique des prédicats est pertinente pour l'analyse des questions liées l'articulation des deux points de vue sémantique et syntaxique dans l'enseignement et l'apprentissage des équations, inéquations et fonctions au secondaire.
Pour compléter les éclairages apportés par la sémantique logique, nous avons conduit une étude historique circonscrite des relations entre ces concepts mathématiques. Nous avons ainsi croisé cette étude avec notre perspective logique en vue de repérer la dyade sémantique/ syntaxe au moment de la formation de ces concepts.
La question principale étudiée dans l'exploration didactique concerne la possibilité de repérer, dans le développement des concepts d'équation, d'inéquation et de fonction, des phénomènes liés à la dialectique sémantique / syntaxe. Pour cela, nous avons conduit une analyse des programmes et des manuels de l'enseignement secondaire tunisien ; soumis un questionnaire à des élèves du secondaire et des étudiants de classes préparatoires ; proposé une situation d'apprentissage à quelques élèves volontaires et réalisé quelques entretiens avec des enseignants. Nos travaux montrent un recul du point de vue sémantique dès que les techniques syntaxiques sont disponibles, et une quasi absence d'articulation entre syntaxe et sémantique.

Full textThe thesis consists of three parts. In Part I, we consider partially overdeterminedboundary-value problemS for Laplace PDE in a planar simply connected domain withLipschitz boundary. Assuming Dirichlet and Neumann data available on its part to be realvaluedfunctions of certain regularity, we develop a non-iterative method for solving thisill-posed Cauchy problem choosing as a regularizing parameter L2 bound of the solutionon complementary part of the boundary. The present complex-analytic approach alsonaturally allows imposing additional pointwise constraints on the solution which, onpractical side, can help incorporating outlying boundary measurements without changingthe boundary into a less regular one. Part II is concerned with spectral structure of atruncated Poisson operator arising in various physical applications. We deduce importantproperties of solutions, discuss connections with other problems and pursue differentreductions of the formulation for large and small values of asymptotic parameter yieldingsolutions by means of solving simpler integral equations and ODEs. In Part III, we dealwith a particular inverse problem arising in real physical experiments performed withSQUID microscope. The goal is to recover certain magnetization features of a sample frompartial measurements of one component of magnetic field above it. We develop newmethods based on Kelvin and Fourier transformations resulting in estimates of netmoment components
Lu, Hoang-Chinh. "Equations hessiennes complexes." Toulouse 3, 2012. http://thesesups.ups-tlse.fr/1961/.
Full textIn this thesis we study the complex hessian equations locally in Cn and globally on compact manifolds. In the first chapter, we study finite energy classes of Cegrell's type on m-hyperconvex domain. We then use a varational method to solve the complex hessian equation with rather singular right hand side. In the second chapter, we solve a degenerate complex hessian equation on compact Kahler manifolds with the right hand side also depends on the unknown and belongs to some Lp space. The last chapter is devoted to a viscosity approach which is a very efficient method to solve real degenerate elliptic equations of second order. It is recently used in the complex case. This method allows us to obtain a new existence and uniqueness result in the case of hermitain homogeneous compact manifolds

Full textIn this thesis, we refine the notion of almost automorphic functions on time scales introduced in the literature by Lizama and Mesquita, we explore some new properties of such functions and apply the results to study the existence and uniqueness of almost automorphic solution for a new class of dynamic equations on time scales. Then we introduce the concept of almost automorphic functions of order n on time scales, we investigate the fundamental properties of these functions and we use the findings to establish the existence and uniqueness and the global stability of almost automorphic solution of one to a first order dynamical equation with finite time varying delay. Then we present the concept of asymptotically almost automorphic functions of order n on time scales. We study the properties of these functions and we use the results to prove, under suitable hypothesis, that the unique solution to a problem with initial condition is asymptotically almost automorphic of order one at the one hand, and the existence and uniqueness of asymptotically almost automorphic solution for an integro-dynamic equation with nonlocal initial conditon on time scales in other hand. Finally, using the concept of semigroup on time scales introduced by Hamza and Oraby, we generalize the results in Lizama and Mesquita's paper for abstract Banach spaces, that is, we study the existence and uniqueness of almost automorphic solution for semilinear abstract dynamic equations on time scales
Sedrakyan, Hayk. "Comportement limite des systèmes singuliers et les limites de fonctions valeur en contrôle optimal." Thesis, Paris 6, 2014. http://www.theses.fr/2014PA066681/document.
Full textThis thesis consists of two main parts. In the first part, Chapter 3 is devoted to the investigation of the limit behavior of a singularly perturbed control system with two state variables which are weakly coupled. In order to prove our approximation result we use the so called averaging method and a recent result on nonexpansive control. The main novelty of our averaging approach lies in the fact that the limit dynamic may depend on the initial condition of the fast system. In the literature, the investigation of the limit behavior of such systems has been usually addressed under conditions that ensure that the limit dynamic is independent from the initial condition of the fast system. In Chapter 4, we generalise the results of Chapter 3 by considering a more general nonexpansivity condition. Moreover, we consider an example where the new nonexpansity condition is satisfied but the nonexpansivity condition of Chapter 3 does not hold true. The second part deals with Hamilton-Jacobi equations under state constraints. Chapter 5 focuses on the stable representation of convex Hamiltonians by functions describing a Bolza optimal control problem. In Chapter 6 we investigate stability of solutions of Hamilton-Jacobi-Bellman equations under state constraints by studying stability of value functions of a suitable family of Bolza optimal control problems under state constraints. We show that under suitable assumptions, the value function is a unique viscosity solution to Hamilton-Jacobi-Bellman equation and that solutions are stable with respect to Hamiltonians and state constraints
