Um modelo para controle biológico de pragas associado ao uso de pesticidas
(Universidade Federal de Santa Maria, 2014-04-10)
In this work we propose a Coupled Map Lattice to study a predador-prey system where
the prey is a pest and the predador is a biological control agent. We consider that the
strategy of biological pest control is combined ...

Retratos de fase de uma família de sistemas quadráticos planares integráveis com duas parábolas invariantes
(Universidade Federal de Santa Maria, 2021-05-07)
In this work we prove the Grobman-Hartman Theorem and the Local Stable Manifold
Theorem, classical results in the study of the local behavior of the solutions of nonlinear
differential equations. Then we provide the ...
Gráficos de curvatura média constante com bordo prescrito satisfazendo a condição de declividade limitada
(Universidade Federal de Santa Maria, 2011-04-08)
We study problems of existence and uniqueness of constant mean curvature surfaces with prescribed boundary satisfying the bounded slope condition. The surfaces
are given as Euclidean graphs in R3 and as parabolic graphs ...
Superfícies duplamente conexas de curvatura média constante com bordo prescrito em planos paralelos
(Universidade Federal de Santa Maria, 2008-12-12)
In this work we presented some existence results about constant mean curvature surfaces in R³ with prescribed boundary in parallel planes, topologically an annulus,
that are obtained by solving Dirichlet s problems for ...
O problema de Dirichlet para a equação da hipersuperfícies mínimas em domínios limitados
(Universidade Federal de Santa Maria, 2014-07-22)
In this work we study the classical results of existence and non-existence of solutions for the Dirichlet problem for the minimal hypersurfaces equation in bounded domains of Rn due to Jenkins-Serrin [8].
Modelos matemáticos para evolução de resistência de insetos-praga a transgênicos
(Universidade Federal de Santa Maria, 2021-04-30)
Genetically Modified Organisms (GMOs) are organisms that have undergone artificial
changes in their genetic material. We can cite as an example of GMOs, genetically modified
crops or, simply, transgenic crops. The main ...
Cografos integrais
(Universidade Federal de Santa Maria, 2021-09-16)
The search for integral cographs is a topic of interest in Spectral Graph Theory. From this,
and motivated by the structural characteristics of these graphs, and by their spectral properties,
we propose, in this dissertation, ...
Vértices, curva focal e superfície focal de curvas no espaço
(Universidade Federal de Santa Maria, 2013-03-19)
The focal surface of a curve γ in the Euclidean 3-space is defined as the envelope of the normal
planes of γ. The focal surface of γ is singular along a curve Cγ, called the focal curve or generalized
evolute. This curve ...
