Zg. Lu et Wd. Wang, GLOBAL STABILITY FOR 2-SPECIES LOTKA-VOLTERRA SYSTEMS WITH DELAY, Journal of mathematical analysis and applications, 208(1), 1997, pp. 277-280
In this paper, a two-species delayed Lotka-Volterra system without del
ayed intraspecific competitions is considered. It is proved that the s
ystem is globally stable for all off-diagonal delays pi(12), tau(21) g
reater than or equal to 0, if and only if the interaction matrix of th
e system satisfies Condition (WDD). (C) 1997 Academic Press.
