Permanence, oscillation and attractivity of the discrete hematopoiesis model with variable coefficients Original Research Article

In this paper, we consider the nonlinear delay difference equation with periodic coefficients View the MathML sourcepn+1−pn=−δnpn+βn1+(pn−ω)m Turn MathJax on and demonstrate that solutions are permanent. The existence of a positive periodic solution is proven and sufficient conditions for the attractivity of this solution are obtained. Oscillation and nonoscillation about the positive periodic solution is considered.
