Повний текст джерелаThis thesis studies the widespread natural phenomenon of synchronization, which was first observed by Huygens en 1665. On the basis of the results on the exact boundary controllability, for a coupled system of wave equations with Neumann boundary controls, we consider its exact boundary synchronization (by groups), as well as the determination of the state of synchronization. Then, we consider the exact boundary controllability and the exact boundary synchronization (by groups) for the coupled system with coupled Robin boundary controls. Due to difficulties from the lack of regularity of the solution, we have to face a bigger challenge. In order to overcome this difficulty, we take advantage of the regularity results for the mixed problem with Neumann boundary conditions (Lasiecka and Triggiani) to discuss the exact boundary controllability, and by the method of compact perturbation, to obtain the non-exact controllability for the system

Повний текст джерелаThe purpose of this thesis is the factorization of elliptic boundary value problems defined in cylindrical domains, in a system of decoupled first order initial value problems. We begin with the Poisson equation with mixed boundary conditions, and use the method of invariant embedding: we embed our initial problem in a family of similar problems, defined in sub-domains of the initial domain, with a moving boundary, and an additional condition in the moving boundary. This factorization is inspired by the technique of invariant temporal embedding used in Control Theory when computing the optimal feedback, for, in fact, as we show, our initial problem may be defined as an optimal control problem. The factorization thus obtained may be regarded as a generalized block Gauss LU factorization. From this procedure emerges an operator that can be either the Dirichlet-to-Neumann or the Neumann-to-Dirichlet operator, depending on which boundary data is given on the moving boundary. In any case this operator verifies a Riccati equation that is studied directly by using an Yosida regularization. Then we extend the former results to more general strongly elliptic operators. We also obtain a QR type factorization of the initial problem, where Q is an orthogonal operator and R is an upper triangular operator. This is related to a least mean squares formulation of the boundary value problem. In addition, we obtain the factorization of overdetermined boundary value problems, when we consider an additional Neumann boundary condition: if this data is not compatible with the initial data, then the problem has no solution. In order to solve it, we introduce a perturbation in the original problem and minimize the norm of this perturbation, under the hypothesis of existence of solution. We deduce the normal equations for the overdetermined problem and, as before, we apply the method of invariant embedding to factorize the normal equations in a system of decoupled first order initial value problems.

Повний текст джерелаEn este trabajo se aborda el problema de existencia de algunos tipos de soluciones para las ecuaciones de ondas en el agua así como la relación que existe entre estas soluciones y la forma de un fondo impermeable sobre la que se desliza el fluido. Empezamos por describir las ecuaciones que modelan el fenómeno físico a partir de las leyes de conservación; el modelo general de las ecuaciones de ondas en el agua, escrito para la restricción de la velocidad potencial a la superficie libre, es \begin{equation*} \left\{ \begin{aligned} &\partial_t\zeta-G(\zeta,b)\psi=0, \\ &\partial_t\psi+g\zeta+\frac{1}{2}|\nabla_X\psi|^2-\frac{1}{2(1+|\nabla_X\zeta|^2)}(G(\zeta,b)\psi+\nabla_X\zeta\cdot\nabla_X\psi)^2=0, \end{aligned} \right. \end{equation*} donde $G=G(\zeta,b)\psi$ es el operador Dirichlet-Neumann, el cual contiene la información del fondo $b$, \begin{equation*} G(\zeta,b)\psi:=-\sqrt{1+|\nabla_X\zeta|^2}\partial_n\phi|_{y=\zeta(t,X)}, \end{equation*} y \begin{equation*} \left\{ \begin{array}{rl} & \Delta\phi=0, \quad \R\times(b,\zeta), \\ & \phi|_{y=\zeta}=\psi, \quad \partial_n \phi|_{y=b(X)}=0. \end{array} \right. \end{equation*} Después de describir las condiciones para un teorema de existencia y unicidad de soluciones de las ecuaciones de ondas en el agua, en espacios de Sobolev, nos preguntamos sobre el mínimo de datos necesarios, sobre la superficie libre, para identificar el fondo de manera única. Por la relación que existe entre el operador Dirichlet-Neumann y la velocidad dentro del fluido y utilizando la propiedad de continuación única de las funciones armónicas hemos probado que basta conocer el perfil, la velocidad potencial y la velocidad normal en un instante de tiempo dado y un abierto de $\R$, aún cuando nuestro sistema es de evolución. En la segunda parte se estudia la existencia de soluciones en forma de salto hidráulico para las ecuaciones estacionarias de ondas en el agua, en dimensión dos y su relación con la velocidad aguas arriba, caracterizada por un parámetro adimensional, llamado el número de Froude, $F$, como consecuencia de la existencia de ramas de bifurcación de la solución trivial para el problema \begin{equation*} \mathcal{F}(\eta,F)=\eta+F\widetilde{\psi}_{y^{\prime }}+\frac{\epsilon}{2}(% \widetilde{\psi}_{x^{\prime }}^2+\widetilde{\psi}_{y^{\prime }}^2)-\epsilon^2\eta_x\widetilde{\psi}_{x^{\prime }}\widetilde{\psi}% _{y^{\prime }}+\frac{\epsilon^3}{2}\eta_x^2\widetilde{\psi}_{y^{\prime }}^2; \end{equation*} donde \begin{equation*} \left\{ \begin{aligned} &\Delta\widetilde{\psi}=\epsilon G, && (-L,L)\times(0,1), \\ &\widetilde{\psi}_{x'}=0, && x'=-L,L, \\ &\widetilde{\psi}=0, && y'=0, \\ &\widetilde{\psi}=-F\eta, && y'=1. \end{aligned} \right. \end{equation*}
