Convergence to equilibria in discrete population models

Abstract

For a family of difference equations where and is continuous and decreasing, we find sufficient conditions for the convergence of all solutions to the unique positive equilibrium. In particular, we improve, up to our knowledge, all previous results on the global asymptotic stability of the equilibrium in the particular cases of the discrete Mackey–Glass and Lasota–Wazewska models in blood-cells production.
