Jh. Wu et Yq. Zhao, PERMANENCE AND CONVERGENCE IN MULTISPECIES COMPETITION SYSTEMS WITH DELAY, Proceedings of the American Mathematical Society, 126(6), 1998, pp. 1709-1714
The permanence and global attractivity of positive equilibria are obta
ined for some multi-species Kolmogorov competition models with delay b
y embedding the system into a larger cooperative system with delay and
then appealing to the theory of monotone dynamical systems.
