Global attractivity in population dynamics
We established sufficient conditions for the global attractivity of the positive equilibrium of the delay differential equation N(t)=−mu;N(t)+∑i=1m pi exp[−γN(t−τi)], t⩾0, m⩾1. For m = 1, equation (1) was used by Wazewska-Czyzewska and Lasota as a model for the survival of red-blood cells in an animal.
