Existência, unicidade e estabilidade de solução para um problema termoelástico hiperbólico com domínio não limitado em R
(Universidade Federal de Santa Maria, 2019-08-29)
Consider the Cauchy Problem which describes the dynamics of linear
rafters vibrations in R subjected to thermal e ects modeled by the Cattaneo
law.
We will focus our attention on obtaining the existence and uniqueness

Modelos discretos para dinâmica hospedeiro-parasitoide-predador
(Universidade Federal de Santa Maria, 2019-10-17)
In this work, we formulate discrete models, described by Difference Equations and Coupled
Map Lattices, in order to analize the local and spatio-temporal dynamics of hostparasitoid-
predator dynamics. We firstly consider ...
Modelos discretos para agregação populacional
(Universidade Federal de Santa Maria, 2019-12-12)
The mechanisms that can lead to the formation of heterogeneous distribution of individuals
of many biological species arouse the interest of researchers from various areas. Many
mathematical models of pattern formation ...
O problema de Dirichlet para a equação das hipersuperfícies mínimas em domínios arbitrários de uma variedade Riemanniana
(Universidade Federal de Santa Maria, 2018-08-22)
In this work we study the Dirichlet problem for the minimal graph equation on C2-domains Ω ⊂ M , where M is an arbitrary complete Riemanniam manifold. We show that, in the case where Ω is bounded, for ϕ ∈ C2(∂Ω), there ...

A filtração standard de uma álgebra de Hopf
(Universidade Federal de Santa Maria, 2014-03-25)
In this work we present the lifting method [AS2], which is used to classify certain class of Hopf algebras. Since this method is based on the coradical filtration, it can be used just for those Hopf algebras satisfying the ...
Existência de solução para um problema envolvendo uma equação diferencial fracionária
(Universidade Federal de Santa Maria, 2019-11-06)
This paper aims to present results that guarantee the existence of solution to a problem
involving a fractional differential equation with antiperiodic boundary conditions. The
fractional differential equation considered ...
Uso da base dinâmica em um sistema de duas vigas acopladas
(Universidade Federal de Santa Maria, 2013-08-26)
This work researches on free and forced vibrations of a double beam coupled system. The
system is regarded as two Euler-Bernoulli beams which are parallel, have the same length,
are simply supported and are connected ...

Bordo assintótico de superfícies mínimas em H2 × R
(Universidade Federal de Santa Maria, 2020-02-27)
In this work, we present some examples of minimal surfaces in H2 × R, and also a description
of the product and geodesic boundary of these surfaces. Our main goal is to
prove Theorem 5.1 of the Kloeckner and Mazzeo’s ...
