Bifurcação e estabilidade de equilíbrios de um problema de Neumann parabólico com peso indefinido em genética populacional
(Universidade Federal de São Carlos, 2015-03-30)
This work is concerned with a semilinear parabolic partial differential equation under a homogeneous Neumann boundary condition occuring in population genetics. It describes the evolution of gene frequencies under selection ...
Operadores lineares em espaços de Hardy
(Universidade Federal de São Carlos, 2015-03-13)
The present work aims to present an example of linear a functional defined on a dense subspace of the Hardy space H1(Rn) to be built, with the intention of showing that despite the fact that this functional is uniformly ...
O princípio do máximo de Omori-Yau e generalizações
(Universidade Federal de São Carlos, 2014-01-31)
In this work we seek to establish a first contact with Geometric Analysis, aiming the understanding of the Good Shadow Principle of Fontenele and Xavier ([FX11]), which is a generalization of the Omori-Yau Principle. We ...
Exemplos de T-espaços e T-ideais infinitamente gerados
(Universidade Federal de São Carlos, 2014-08-14)
Let F be a field of characteristic p ≥ 3. Denote by F0(X) and F1(X) the free associative algebras without and with unity, respectively, freely generated by the infinite set X. In this dissertation we study T-spaces ...
Espaços de Hardy e compacidade compensada
(Universidade Federal de São Carlos, 2014-03-13)
This work is divided into two parts. In the first part, our goal is to present the theory of Hardy Spaces Hp(Rn), which coincides with the Lebesgue space Lp(Rn) for p > 1, is strictly contained in Lp(Rn) if p = 1, and is ...
Tópicos sobre funções de várias variáveis complexas
(Universidade Federal de São Carlos, 2015-03-27)
This work shows classical results of analysis of holomorphic functions of both one and several complex variables. Are treated as main topics results on integral representations of holomorphic functions, approximation by ...
Recobrimentos ramificados entre superfícies e 2-orbifolds geométricos
(Universidade Federal de São Carlos, 2014-10-22)
The purpose of this work is to study the realizability problem of branched coverings between closed, connected and orientable surfaces. For each covering, there exists a set of naturally associated data called branch datum ...
Representações dos grupos simétrico e alternante e aplicações às identidades polinomiais
(Universidade Federal de São Carlos, 2014-11-28)
In this dissertation we ll present a discussion about the Representations of the Symmetric Group Sn and Alternating Group An. We ll study basics results of the Young s Theory about the representations of the Symmetric Group ...
Classes de Reidemeister para coincidências entre secções de um fibrado
(Universidade Federal de São Carlos, 2014-03-28)
In this work we study the theory of Reidemeister coincidence classes for coincidences between two sections s; f : B → E de um fibrado q : E → B, both the algebraic treatment by the Reidemeister action and the ...
Análise de um método de elementos finitos com interface estabilizada para a equação de advecção - reação
(Universidade Federal de São Carlos, 2014-08-07)
In this study we present an interface stabilised finite element method for the scalar advection-reaction equation... (CONTINUA - VER NO PDF)
