Abstract :
A discrete-time competitive system with two species, multi-delays and fluctuating environment is considered. New sufficient conditions to guarantee the permanence of the ecosystem are obtained. An example is given to show that the results obtained in this paper are necessary complements to those related with this biomathematical model.
