| Abstract: | This paper is devoted to considering the existence of saddle separatries cycle of the Volterra Predator-prey System Under sparse effect, where L>0. In my master's degree paper, we had studied the existence of saddle separatries cycle under special condition. This paper is to consider the problem under general condition, therefore the conclusion in the paper has more practicality. The conclusion has made a base for studying the existence and uniqueness of limit cycle in the mean time. |
