摘要
研究差分方程 的全局吸引性。用二次选代法导出方程的零解全局吸引的—族 新的充分条件,将结果应用于Logistic差分方程及Michelis-Menten差分模型,所得推论改进了已有结果.
Consider the difference equation , by a new method, the sufficient conditions that guarantee every solution of the equation to convergence to zero were to obtained. The results were applied to the logistic model and Micheals-Menten model, some known results were improved.
