O ciclo de crescimento de Goodwin: um modelo de dinâmica econômica não linear
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2011)
Este estudo analisa o ciclo de crescimento de Goodwin (ou modelo de Goodwin) em sua formulação original, através da apresentação de suas propriedades e características. O modelo de Goodwin é semelhante ao modelo presa-predador ...
Dois ensaios sobre aspectos da instabilidade financeira
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2014)
This master thesis presents two papers devoted to Minsky’s theory of financial instability. Studies have as starting point LIMA and MEIRELLES (2007). The objective is to develop a macrodynamic model where the following ...

Influencia de la deficiencia de nitrógeno y fósforo en las interacciones competitivas entre Chlorella vulgaris Y Scenedesmus acutus
(2010)
En el presente trabajo se estudió la respuesta de las especies cloroficeas Chlorella vulgaris y Scenedesmus acutus ante la deficiencia de los macronutrientes fósforo y nitrógeno y las implicaciones que esto tiene sobre sus ...
Repeating games and dynamical systems in oil marketJuegos repetitivos y sistemas dinámicos en el mercado del petroleo
(2010-04-16)
We use the modern theory of repetitive games in a model that help understand a market with a cartel like OPEP. We also study a dynamical system Lotka-Volterra type, and we analyze the dynamic behavior of the model.

Parameter estimation of a predator-prey model using a genetic algorithm
(2010-01-01)
This paper presents the parameter estimation of a biological system with real data extracted from literature, and different model structures: Lotka-Volterra model (basic predator-prey model) and saturation predator-prey ...
Existence of local and global solution for a spatio-temporal predator-prey modelExistencia de solución local y global para un modelo espacio-temporal depredador-presa
(Universitas Scientiarum, 2019)
In this paper we prove the existence and uniqueness of weak solutions for a kind of Lotka–Volterra system, by using successive linearization techniques. This approach has the advantage to treat two equations separately in ...
Environmental fluctuations and their consequences for the evolution of phenotypic diversity
(Frontiers Media SA, 2017-05)
An essential aspect of the current theory of adaptive speciation is the maintenance of phenotypic variation and the evolution of stationary stable phenotypic diversity, a phenomenon known as evolutionary branching. Theoretical ...
