| Abstract: | The n-species Lotka-Volterra systems is considered. Firstly the relationship between non-negative equilibria of this system is investigated, and then some new necessary and sufficient conditions for the permanence of n-species Lotka-Volterra systems are obtained. The criterions given in this paper are easier to carry out than the other results obtained in the past. |
