Existência de múltiplas soluções para classes de problemas elípticos com função peso mudando de sinal em domínios ilimitados
(Universidade Federal de São Carlos, 2009-03-20)
The aim of this work is to give some suficient conditions for the existence and multiplicity of the solutions for a class of elliptic problems with sign-changing weight function in unbounded domains, using for this variational ...
Sincronização e continuidade em um problema parabólico governado pelo p-Laplaciano
(Universidade Federal de São Carlos, 2009-02-16)
In this work we study a reaction diffusion problem governed by the p-laplacian with p > 2 and we analyze properties of the continuity of the set of equilibria with respect to the diffusion parameter. We also consider coupled ...

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

A fórmula de aproximação de Baouendi -Treves
(Universidade Federal de São Carlos, 2009-03-06)
Let be a N-dimensional smooth manifold. Consider a locally integrable structure L of CT with fiber dimension 1 ≤ n < N and set m = N − n. We say that L is locally integrable if, for every p ∈ , there ...
Pontos fixos e os contra-exemplos de Jiang
(Universidade Federal de São Carlos, 2009-02-27)
The aim of this work is construct the example, presented by Boju Jiang, of a self - map on a manifold with non - realizable Nielsen number. Firstly we will need to present the fixed point
theory and some results about ...
Graduações de grupo na álgebra das matrizes triangulares superiores
(Universidade Federal de São Carlos, 2009-08-11)
In this work we study group gradings on the upper triangular matrices algebra UTn(F), which have several applications in the PI-algebra theory. Our main purpose is to exhibit a description of all _nite gradings of UTn(F) ...
Existência de padrões com difusibilidade variável e condição de fronteira de Neumann não linear
(Universidade Federal de São Carlos, 2009-03-24)
In this work we study a reaction-difusion problem with nonlinear Neumann boundary condition. The objective is to present suficient conditions on the diffusion coeficient so that the problem has an stable nonconstant ...
Operadores de Calderón-Zygmund e o teorema T1
(Universidade Federal de São Carlos, 2009-04-14)
In this work, we present necessary and suficient conditions for that an operator of Calderón-Zygmund type can be extended to a bounded operator on L2. By using results of interpolation and cancellation conditions on the ...
