The effect of delays on the permanence for Lotka-Volterra systems. (English) Zbl 0833.34071
The authors give certain examples which show that Kuang’s conjecture [see Y. Kuang, Delay differential equations with applications in population dynamics, Academic Press (1993; Zbl 0777.34002), p. 310] is not true.
