Full textThis memoir presents the results obtained during my PhD, whose goal is the study of the controllability of some Partial Differential Equations.The first part of this thesis is concerned with the study of the controllability of some kinetic equations undergoing different regimes. Under a collisional regime, we study the controllability of the Kolmogorov equation, a particular case of kinetic Fokker-Planck equation, in the phase space $R^d times R^d$. We obtain the null-controllability of this equation thanks to the use of a spectral inequality associated to the Laplace operator in the whole space. Under a non-collisional regime, we study the controllability of two fluid-kinetic models, the Vlasov-Stokes system and the Vlasov-Navier-Stokes system, which exhibe nonlinearities due to the coupling terms. In those cases, the strategy relies on the Return method.In the second part, we study the controllability of a family of 1-D degenerate parabolic equations by the flatness method, which allows the construction of explicit controls.The third part is focused on the problem of the controllability of the Schrödinger equation via domain deformations, i.e., using the domain as a control. We obtain a result of this kind in the case of the two-dimensional unit disk, for radial data. Our methods are based on a local exact controllability result around a certain trajectory, obtained thanks to the Inverse Mapping theorem

Full textEsta tesis esta dividida en seis partes. La primera parte está dedicada a probar propiedades de Hadamard y teoremas del tipo de Liouville para soluciones viscosas de ecuaciones diferenciales parciales elípticas completamente no lineales con término gradiente \begin{equation}\label{eq06-10-13 1} \mathcal{M}^{-}(|x|,D^2u)+\sigma(|x|)|Du|+f(x,u)\leq 0,\quad \ x\in\Omega, \end{equation} donde $\Omega=\mathbb{R}^N$ o un dominio exterior, las funciones $\sigma:[0,\infty)\to\mathbb{R}$ y $f:\Omega\times (0,\infty)\to (0,\infty)$ son continuas las cuales satisfacen algunas condiciones extras. En la segunda parte se estudia la existencia de soluciones que explotan en la frontera para ecuaciones elípticas fraccionarias semilineales \begin{equation}\label{eq06-10-13 2} \arraycolsep=1pt \begin{array}{lll} (-\Delta)^{\alpha} u(x)+|u|^{p-1}u(x)=h(x),\quad & x\in\Omega,\\[2mm] \phantom{ (-\Delta)^{\alpha} u(x)+|u|^{p-1}} u(x)=0,\quad & x\in\bar\Omega^c,\\[2mm] \phantom{ (-\Delta)^{\alpha} \ } \lim_{x\in\Omega, x\to\partial\Omega}u(x)=+\infty, \end{array} \end{equation} donde $p>1$, $\Omega$ es un dominio abierto acotado $C^2$ de $\mathbb{R}^N(N\geq2)$, el operador $(-\Delta)^{\alpha}$ con $\alpha\in(0,1)$ es el Laplaciano fraccionario y $h:\Omega\to\R$ es una función continua la cual satisface algunas condiciones extras. Por otra parte, analizamos la unicidad y el comportamiento asimptótico de soluciones al problema (\ref{eq06-10-13 2}). El objetivo principal de la tercera parte es investigar soluciones positivas para ecuaciones elípticas fraccionarias \begin{equation}\label{eq06-10-13 3} \arraycolsep=1pt \begin{array}{lll} (-\Delta)^{\alpha} u(x)+|u|^{p-1}u(x)=0,\quad & x\in\Omega\setminus\mathcal{C},\\[2mm] \phantom{ (-\Delta)^{\alpha} u(x)+|u|^{p-1}} u(x)=0,\quad & x\in\Omega^c,\\[2mm] \phantom{ (-\Delta) \ } \lim_{x\in\Omega\setminus\mathcal{C}, \ x\to\mathcal{C}}u(x)=+\infty, \end{array} \end{equation} donde $p>1$ y $\Omega$ es un dominio abierto acotado $C^2$ de $\mathbb{R}^N(N\geq2)$, $\mathcal{C}\subset \Omega$ es el frontera de dominio $G$ que es $C^2$ y satisface $\bar G\subset\Omega$. Consideramos la existencia de soluciones positivas para el problema (\ref{eq06-10-13 3}). Mas aún, analizamos la unicidad, el comportamiento asimptótico y la no existencia al problema (\ref{eq06-10-13 3}). En la cuarta parte, estudiamos la existencia de soluciones débiles de (F) $ (-\Delta)^\alpha u+g(u)=\nu $ en un dominio $\Omega$ abierto acotado $C^2$ de $\R^N (N\ge2)$ el cual se desvanece en $\Omega^c$, donde $\alpha\in(0,1)$, $\nu$ es una medida de Radon y $g$ es una función no decreciente satisfaciendo algunas hipótesis extras. Cuando $g$ satisface una condición de integrabilidad subcrítica, probamos la existencia y unicidad de una solución débil para el problema (F) para cualquier medida. En el caso donde $\nu$ es una masa de Dirac, caracterizamos el comportamiento asimptótico de soluciones a (F). Asimismo, cuando $g(r)=|r|^{k-1}r$ con $k$ supercrítico, mostramos que una condición de absoluta continuidad de la medida con respecto a alguna capacidad de Bessel es una condición necesaria y suficiente para que (F) sea resuelta. El propósito de la quinta parte es investigar soluciones singulares débiles y fuertes de ecuaciones elípticas fraccionarias semilineales. Sean $p\in(0,\frac{N}{N-2\alpha})$, $\alpha\in(0,1)$, $k>0$ y $\Omega\subset \R^N(N\geq2)$ un dominio abierto acotado $C^2$ conteniendo a $0$ y $\delta_0$ la masa de Dirac en $0$, estudiamos que la solución débil de $(E)_k$ $ (-\Delta)^\alpha u+u^p=k\delta_0 $ en $\Omega$ la cual se desvanece en $\Omega^c$ es una solución débil singular de $(E^*)$ $ (-\Delta)^\alpha u+u^p=0 $ en $\Omega\setminus\{0\}$ con el mismo dato externo. Por otra parte, estudiamos el límite de soluciones débiles de $(E)_k$ cuando $k\to\infty$. Para $p\in(0, 1+\frac{2\alpha}{N}]$, el límite es infinito en $\Omega$. Para $p\in(1+\frac{2\alpha}N,\frac{N}{N-2\alpha})$, el límite es una solución fuertemente singular de $(E^*)$. Finalmente, en la sexta parte estudiamos la ecuación elíptica fraccionaria semilineal (E1) $(-\Delta)^\alpha u+\epsilon g(|\nabla u|)=\nu $ en un dominio $\Omega$ abierto acotado $C^2$ de $\R^N (N\ge2)$, el cual se desvanece en $\Omega^c$, donde $\epsilon=\pm1$, $\alpha\in(1/2,1)$, $\nu$ es una medida de Radon y $g:\R_+\mapsto\R_+$ es una funci\'on continua. Probamos la existencia de soluciones débiles para el problema (E1) cuando $g$ es subcrítico. Además, el comportamiento asimptótico y la unicidad de soluciones son descritas cuando $\epsilon=1$, $\nu$ es una masa de Dirac y $g(s)=s^p$ con $p\in(0,\frac)$.
