Existence and Global Attractivity of Positive Periodic Solutions of a Survival Model of Red Blood Cells

摘要

In this paper, we deal with a model for the survival of red blood cells with periodic coefficients, x (t) = -μ (t) x(t) + P (t)e~(-r(t)x(t-τ(t))), t≥0. Some new sufficient conditions are obtained for the existence and global attractivity of positive periodic solutions of the equation.
