(Universidade Federal de Santa Maria, 2015-08-10)
The aim of this work is to establish conditions for the existence and multiplicity of solutions
for Ambrosetti-Prodi problems type involving pLaplacian operator with subcritical growth
related to the Sobolev critical ...
Existência de soluções para um problema do tipo (p; q)-Laplaciano com perturbação
(Universidade Federal de Santa Maria, 2015-08-10)
In this paper, considering _ RN (N > 2) a bounded smooth domain, using blow-up
techniques and the Leray Schauder Topological Degree theory, we intend to ensure the
existence of positive solutions for a problem involving ...
Resolubilidade global de operadores lineares com coeficientes constantes
(Universidade Federal de Santa Maria, 2013-07-15)
In this dissertation we present a proof of a Bernard Malgrange theorem, which
establishes a necessary and sufficient condition for the global solvability of a linear
operator with constant coefficients.
Pares admissíveis, sistemas admissíveis e biálgebras na categoria dos módulos de Yetter-Drinfeld
(Universidade Federal de Santa Maria, 2014-03-19)
The purpose of this work is to study the relationships between admissible pairs, systems admissible and bialgebras in the category of Yetter-Drinfeld modules, as well as some properties of the Hopf algebra associated (via ...

O teorema de Cauchy em equações de Navier-Stokes
(Universidade Federal de Santa Maria, 2013-03-08)
This work presents the Cauchy's theorem in its classical form, and aims to weaken their
hypotheses, providing a more advantageous use in continuum mechanics. The methodology
is axiomatic, that is, basic concepts are ...
Estudo das vibrações transversais em um sistema viscoelástico acoplado de duas cordas
(Universidade Federal de Santa Maria, 2013-11-22)
In this work, it is developed a study of the transverse vibrations of a system composed
by two parallel strings of equal length, coupled by a viscoelastic element. The frequencies
and mode shapes are obtained using modal ...
Soluções fundamentais de operadores lineares de coeficientes constantes
(Universidade Federal de Santa Maria, 2012-03-09)
In this thesis we present a proof of the Malgrange-Ehrenpreis theorem, which states that every operator with constant coefficients non identically zero has a fundamental solution.
Um modelo discreto para interações planta-herbívoro-predador
(Universidade Federal de Santa Maria, 2015-06-10)
The population dispersion is an important process to be considered when we wish
analyze the interactions between populations. Taking into account the range and the
way in which the movement takes place makes the model ...
Existência e multiplicidade de soluções positivas para uma classe de problemas elíticos
(Universidade Federal de Santa Maria, 2014-02-17)
The aim of this work is to give some sufficient conditions for the existence and multiplicity of the solutions for a class of elliptic problems, using for this variational methods, such as Montain Pass Theorem and the ...
