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…
