The introduction of concepts of Game Theory and Ordinary Differential Equations into
Biology gave birth to the field of Evolutionary Stable Strategies, with applications in Biology …

In this paper we study the phase portraits in the Poincaré disk of the reversible vector fields
of type (2; 0) having generic bifurcations around a symmetric singular point p. We also prove …

A class of left-invariant second order reversible systems with functional parameter is
introduced which exhibits the phenomenon of robust integrability: an open and dense …

Neste trabalho veremos os retratos de fase, no disco de Poincaré, das formas normais
locais das singularidades simétricas dos campos reversíveis do tipo (2; 0) e (2; 1) de baixa …
