摘要
For the blood cell production model dx/dt - -alpha x(t) + F-0 theta(n)/theta(n) + x(n)(t - tau)' we review known results. Permanence of solutions, oscillation and stability of a positive equilibrium or a positive periodic solution are analyzed for non-autonomous generalizations of this equation, with both concentrated and distributed delays.
