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 ...
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, ...
Mergulho de superfície mínima e curvatura total de seu bordo
(Universidade Federal de Santa Maria, 2021-10-07)
Given a minimal submanifold Σn ⊂ Rm with compact boundary Γn−¹, in this work we
analyze under which conditions on Γ we can conclude that Σ is embedded. We show that if a
simple closed curve Γ ⊂ Rm, piecewise regular and ...
