The Classification on the Global Phase Portraits of Two-dimensional Lotka–Volterra System

Journal of Dynamics and Differential Equations, 2008
The authors present a complete classification of all quadratic planar Lotka-Volterra systems. By a very detailed investigation, they find 143 topologically inequivalent global phase portraits for these systems, up to time reversal. First, all systems with nontrivial closed orbits are examined separately.
