Studies on a Kind of Pest Management SI Model with Impulsive Control Strategies
【摘要】 研究一类具有脉冲控制的害虫管理SI数学模型,运用Floquet理论证明了系统害虫灭绝周期解的全局渐近稳定性,并对所得结论进行了数值模拟.
【Abstract】 A pest management SI model with impulsive control strategies is studied firstly. The globally asymptotical stability of the periodic pest-extinction solution is proved by the Floquet′s theory. Furthermore,those results obtained in this paper are confirmed by numerical simulation.
