- Abstract:
- To study the stability for two-dimensional Lotka-Volterra, the sufficient condition of the stability for two-dimensional Lotka-Volterra system was given by using first integral and vector field. Then the conclusion was extended to general two-dimensional systems and the effectiveness was verified by an example.
