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 ...
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 ...
Preservação de mínimos locais de famílias de funcionais via gama-convergência e aplicações

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 ...
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 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 ...
