摘要 研究了一类具有状态脉冲的两种群竞争Lotka-Volterra系统.利用后继函数和类Poincaré准则,得到了该系统阶1周期解存在及其渐近稳定的充分条件,并用数值模拟验证了主要结论. A two species competitive Lotka-Volterra system with state dependent impulsive effects is investigated. Using the successor function method and analogue of Poincaré criterion,sufficient conditions for the existence and the asymptotical stability of the order-one periodic solutions are obtained. Moreover,numerical simulations are given to illustrate our main results.
