Chaos in predator-prey systems with/without impulsive effect. (English) Zbl 1238.34086
Summary: We prove analytically that the seasonal effect can cause chaos in predator-prey systems. Our method of proof is based on some recent results on topological horseshoes. Some applications in systems with impulsive effect are given.
