Global attractivity of the equilibrium of a nonlinear difference equation

The authors consider the nonlinear difference equation x n + 1 = α x n + x n - k f ( x n - k ) , n = 0 , 1 , ⋯ . 1 where α ∈ ( 0 , 1 ) , k ∈ { 0 , 1 , ⋯ } and f ∈ C 1 [ [ 0 , ∞ ) , [ 0 , ∞ ) ] ( 0 ) with f ' ( x ) < 0 . They give sufficient conditions for the unique positive equilibrium of (0.1) to be a global attractor of all positive solutions. The results here are somewhat easier to apply than those of other authors. An application to a model of blood cell production is given.
