Permanence for two-species Lotka-Volterra cooperative systems with delays.
Lu G, Lu Z. Lu G, et al. Math Biosci Eng. 2008 Jul;5(3):477-84. doi: 10.3934/mbe.2008.5.477. Math Biosci Eng. 2008. PMID: 18616353 Free article.
In this paper, a two-species Lotka-Volterra cooperative delay system is considered, and the relationships between the delays and the permanence are obtained. Some sufficient conditions for the permanence under …

Permanence for two-species lotka-volterra systems with delays.
Lin S, Lu Z. Lin S, et al. Math Biosci Eng. 2006 Jan;3(1):137-44. doi: 10.3934/mbe.2006.3.137. Math Biosci Eng. 2006. PMID: 20361814 Free article.
The permanence of the following Lotka-Volterra system with time delays x '(1) ( t ) = x(1) ( t ) [ r(1) - a(1)x(1) ( t ) + a(11)x(1) ( t - tau(11) ) + a(12)x(2) ( t - tau(12) ) ] x '(2) ( t ) = x(2) ( t ) [ r(2) - a(2)x(2) ( t ) + a(21)x(1) ( t …
