Extinction in a two dimensional Lotka-Volterra system with infinite delay. (English) Zbl 1122.34058
A two-dimensional competitive nonautonomous Lotka-Volterra system is considered with infinite delay for the second variable in the first equation and vice-versa in the second one. A result of {\it S. Ahmad} [Proc. Am. Math. Soc. 117, No. 1, 119--204 (1993; Zbl 0843.34033)] is extended to the present case. The corresponding inequality implies the elimination of the second competitor and the survival of the first one.
