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

Bifurcação de Turing-Hopf em um sistema presa-predador
(Universidade Federal de Santa Maria, 2012-06-04)
In this work we studing a generalized predator-prey system in a spatial domain, in
terms of formation. We show parameter, regions where transcritical, Hopf and Turing
bifurcations appear are presented, and also some ...
Efeito Allee e dispersão não local em processos de invasão
(Universidade Federal de Santa Maria, 2012-03-02)
The main goal of this dissertation is to analyze the role of Allee effect in processes of populations invasion for species that reproduce in discrete time steps and perform longrange movement. These phenomena are described ...
Modelos de redes de mapas acoplados para interações herbívoro-predador
(Universidade Federal de Santa Maria, 2013-04-12)
In this work we propose a discrete predator-prey model with the purpose of analyzing the
spatio-temporal dynamics of herbivorous and their predators. For that, we explicitly consider
the dispersion of both species through ...
