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 ...
Ações de categorias, sistemas e equivalência entre as categorias de sistemas e semigrupos inversos
(Universidade Federal de Santa Maria, 2011-04-08)
Mark V. Lawson, in the book "Inverse Semigroups: The Theory of partial
symmetries", provides a very relevant study of the characteristics of inverse
semigroups, including Wagner-Preston Theorem of Representation, ...
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 ...
O problema de Dirichlet para a EDP da curvatura média constante em variedades de curvatura de Ricci não negativa
(Universidade Federal de Santa Maria, 2018-05-22)
In this work we study the Dirichlet problem for the constant mean curvature equation in
bounded, mean convex and C2; - domains contained in a complete Riemannian manifold.
We show an existence and uniqueness result for ...
