摘要 研究一类具有时滞的两食饵一捕食者生态系统的正平衡点的全局吸引性问题,利用迭代法证明了该系统如正平衡点存在,则必是全局吸引的.所得结果推广了Elettreby M F的有关结果. By applying the iterative method,we show that for a delayed two-prey one-predator system,if the positive equilibrium exists,then it is globally attrative. The results generalize the main results of Elettreby M F.
