摘要
提出了一个具有时滞的非自治差分竞争系统.分别利用差分不等式及Lyapunov离散函数技巧,得到了系统永久持续生存和正解全局吸引的充分条件.数值模拟验证了理论结果的正确性.
A non-autonomous discrete competitive system with delays is proposed. By using the method of difference inequality and Lyapunov-like discrete function,sufficient conditions for the permanence of system and global attractivity of positive solutions of system are de（？）ved,respectively.Numerical simulations are presented to substantiate the analytical results.
