摘 要: 考虑非线性差分方程其中a>0,b≤0,c>0.方程(1)是时滞人口模型的离散模拟.J.W.Rodrigus[7]研究了方程(1)当k=0时正平衡解的振动性和全局渐过稳定性.本文我们获得了方程(1)当k>0时正平衡解全局渐近稳定的充分条件,从而补充了文[7]中结论. Consider the nonlinear difference equationwhich is a discrete analogue of the delay differential equation:J. W. Rodrigus[7]have studied the global asymptotic stability of the positive equilibviuin of Eq. (1)when k=0.In this paper,we will obtain some sufficient conditions of the global asymptotic stability of the unique positiveequilibrium of Eq. (1)when k>0,and so our results extend the results in [7].
