Teoria de Littlewood-Paley e o problema de Cauchy para a equação da onda cúbica
(Universidade Federal de São Carlos, 2010-07-08)
In this work, we study the result of well-posedness for the cubic wave equation
u + u3 = 0 in R3, due to H. Bahouri e J.-Y. Chemin, where the Cauchy data is in
the Homogeneous Sobolev space ̇H3/4(R3) × ̇H−1/4(R3). The ...
Decomposição de Bony e um teorema de regularidade para soluções do sistema de Navier-Stokes
(Universidade Federal de São Carlos, 2008-02-13)
Our main goal is to present a dissertation about the J.-M. Bony's decom-
position for the product of distributions and as application a regularity result, due
to J.-Y. Chemin and N. Lerner, for solutions of the Navier-Stokes's ...
Teoria de invariantes de formas binárias
(Universidade Federal de São Carlos, 2010-03-26)
In this work, we studied article [6], that answers the following questions:how are all covariants of binary forms? What are and how to find the canonicalforms of the binary forms of degree n? Is there a finite generating ...
Soluções ondas viajantes da equação Korteweg-de Vries-Burgers
(Universidade Federal de São Carlos, 2006-12-05)
The aim in this work is to estudy the existence and certain qualitative properties of travellingwave
to the Korteweg-de Vries-Burgers (KdVB) equation. The asymptotic behaviour of these
waves is analysed when ε ↓ ...
Efeito Aharonov-Bohm: extensões auto-adjuntas e espalhamento
(Universidade Federal de São Carlos, 2009-10-05)
In this work we present a study of topics related to the Aharonov-Bohm (AB) e®ect. Our framework is that of nonrelativistic quantum mechanics and we use the point of view of mathematical physics. (1) We study the solenoid ...
Equações de BBM-Burgers generalizadas: resultados de existência e convergência de soluções
(Universidade Federal de São Carlos, 2009-03-26)
O problema pseudoviscoso e a equação de BBM-Burgers estocásticos
(Universidade Federal de São Carlos, 2016-09-30)
This work is divided in two parts: In the first part, we study the convergence of a sequence
of approximating solutions to a solution of the stochastic conservation law, in the additive and
multiplicative case. In the ...
Transformada de Tjurina para singularidades determinantais
(Universidade Federal de São Carlos, 2017-07-19)
We study the Tjurina transforms of determinantal singularities and its properties.
A álgebra graduada associada a uma valorização
(Universidade Federal de São Carlos, 2021-11-30)
We begin this work with a study of the graded algebra associated to a valuation $\nu: K \longrightarrow \Gamma_{\infty}$. We verify that in the cases where the value group is free or the residue field is closed by radicals, ...
Hipoelipticidade global analítica e Gevrey de sublaplacianos sob condições Diofantinas
(Universidade Federal de São Carlos, 2022-09-22)
In this dissertation we consider the problem of global Gevrey regularity for a class of partial differential
operators in the form of a sum of squares of vector fields and we show that these operators are
globally Gevrey ...
