Leis de conservacão escalar: fórmula explícita e unicidade
(Universidade Federal de São Carlos, 2011-03-23)
We study scalar conservation laws, with the deduction of an explicit formula of a smooth solution with compact support, we also present the behavior of the solution given by the formula when the initial value is zero outside ...
Estimativas de magnitudes da dinâmica quântica envolvendo dimensões de Hausdorff e de empacotamento
(Universidade Federal de São Carlos, 2014-03-21)
In this work we approach the nonrelativistic quantum mechanics from the point of view of mathematical physics; we present estimates of some dynamical quantities that are used to describe the return probability to the initial ...
$L^2$ estimates for the operators $ \bar\partial $ and $ \bar\partial_b $
(Universidade Federal de São Carlos, 2019-08-02)
The purpose of this work is to establish sufficient conditions for closed range estimates on $(0,q)$-forms, for some fixed $q$, $1 \leq q \leq n-1$, for $\bar\partial_b$ in both $L^2$ and $L^2$-Sobolev spaces in embedded, ...
Funções Lq ultradiferenciáveis globais e aplicações
(Universidade Federal de São Carlos, 2019-11-20)
The class of global Gevrey functions was introduced recently by Z. Adwan, G. Hoepfner and A. Raich, the elements in these spaces are defined in terms of its derivatives with estimates that depend on sequences. It is know ...
Sobre uma família de equações de evolução não lineares : existência, classificação e instabilidade de soluções ondas viajantes
(Universidade Federal de São Carlos, 2018-03-26)
This thesis is concerned with the orbital instability for a specific class of periodic traveling wave solutions with the mean zero related to the modified Camassa-Holm equation. These solutions, called snoidal waves, are ...
Estabilidade de Standing waves
(Universidade Federal de São Carlos, 2014-03-13)
This work is concerned with the orbital stability of special solutions called "standing waves" for Hamiltonian systems in a real and invariant Hilbert space under the action of a specific group of isometries in such space. ...
Applications of topological degree theory to generalized ODEs
(Universidade Federal de São Carlos, 2019-10-27)
In this work, we present original results concerning the theory of Generalized Ordinary Differential Equations (we write generalized ODEs for short) using tools from the Topological Degree theory. In particular, we proved ...
