Planar Kolmogorov systems with infinitely many singular points at infinity
Érika Diz-Pita, Jaume Llibre, M. Victoria Otero-Espinar
We classify the global dynamics of the five-parameter family of planar Kolmogorov systems \begin{equation*} \begin{split} \dot{y}&=y \left( b_0+ b_1 y z + b_2 y + b_3 z\right), \do…
Global phase portraits of a predator-prey system
Érika Diz-Pita, Jaume Llibre, M. V. Otero-Espinar
We classify the global dynamics of a family of Kolmogorov systems depending on three parameters which has ecological meaning as it modelizes a predator-prey system. We obtain all t…
Phase portraits of a family of Kolmogorov systems depending on six parameters
Érika Diz-Pita, Jaume Llibre, M. Victoria Otero-Espinar
Consider a general -dimensional Lotka-Volterra system with a rational first integral of degree two of the form . The restriction of this Lotka-Volterra system to…
