Abstract
The delay Lotka-Volterra equation is a delay-differential extension of the
well known Lotka-Volterra equation, and is known to have N-soliton solutions.
In this paper, Backlund transformations, Lax pairs and infinite conserved
quantities of the delay Lotka-Volterra equation and its discrete analogue are
constructed. The conserved quantities of the delay Lotka-Volterra equation turn
out to be complicated and described by using the time-ordered product of linear
operators.
