Problemas de autovalores para o p-Laplaciano com distintas condições de fronteira
(Universidade Federal de Santa Maria, 2019-07-25)
The goal of this work is to obtain, through the Ljusternik-Schnirelman principle,
a sequence of eigenvalues for p-Laplacian with Dirichlet, Neumann and Robin-Steklov
boundary conditions, the last one which is a combination ...
Multiplicidade de soluções para um problema envolvendo o operador p-laplaciano fracionário
(Universidade Federal de Santa Maria, 2019-02-22)
The aim of the work is to give, through variational methods, sufficient conditions on a
positive parameter to ensure the existence and multiplicity of solutions for the class of
elliptic problems. Such class of problems ...
Equações de Navier-Stokes: aspectos físicos e solução fraca em espaços de Sobolev
(Universidade Federal de Santa Maria, 2008-12-10)
In this work, based on the Law of conservation of mass and the Newton s second Law, we deducted the equations of Navier-Stokes for the uncompressing fluids. Then we have developed in a detailed way the varying form of ...
Pontos helicoidais e vértices de Darboux de curvas no espaço euclidiano
(Universidade Federal de Santa Maria, 2010-03-11)
The main aim of this work is a study about twistings points and Darboux vertices of n-space curves. We define the concept of twisting of a n-space curve as flattening
point of its tangent indicatrix and show that is ...
Retratos de fase de uma família de sistemas cúbicos planares integráveis com duas parábolas invariantes
(Universidade Federal de Santa Maria, 2022-06-10)
In this work we present results of the qualitative theory of Ordinary Differential Equations
used in the study of planar vector fields. Then, we apply these results to determine the
global phase portrait in the Poincaré ...
O teorema de Cauchy na mecânica dos fluidos
(Universidade Federal de Santa Maria, 2010-12-21)
The present work shows Cauchy's Theorem on its classical form, and it has the objective of weakening their statements, and provides aplications in continuum mechanics. The metodology used here is the axiomatic, that is, a ...
Autofunções e frequências de vibração do modelo Euler-Bernoulli para vigas não-clássicas
(Universidade Federal de Santa Maria, 2011-07-18)
This paper presents a methodology for determining eigenfunctions and frequencies
of the Euler-Bernoulli model for elastic beams that can include damping and devices
located at intermediate or end points of the beam. The ...
Hélices, curvas de Bertrand e superfícies regradas
(Universidade Federal de Santa Maria, 2012-02-27)
This work is designed to study helices and Bertrand curves. A circular helix is characterized by having constant curvature k 6= 0 and constant torsion t . If the ratio t k is constant, the curve is called generalized helix. ...

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 ...
