Abstract

Relations between persistence and ultimate boundedness of the solutions of the Lotka-Volterra systemdx(t)dt=x(t)[r₁-a₁₁x(t-τ)+a₂₂y(t-τ)]dy(t)dt=y(t)[r₂+a₂₁x(t-τ)-a₂₂y(t-τ)]modelling "facultative mutualism" with delayed responses are established and sufficient conditions are obtained for the global attractivity of the positive equilibrium of the delay system.
