Oscillation and global attractivity in a discrete survival red blood cells model

I. Kubiaczyk; S. H. Saker — 2003

Applicationes Mathematicae

We consider the discrete survival red blood cells model (*) $N_{n + 1} - N ₙ = - δ ₙ N ₙ + P ₙ e^{- a N_{n - k}}$ , where δₙ and Pₙ are positive sequences. In the autonomous case we show that (*) has a unique positive steady state N*, we establish some sufficient conditions for oscillation of all positive solutions about N*, and when k = 1 we give a sufficient condition for N* to be globally asymptotically stable. In the nonatonomous case, assuming that there exists a positive solution Nₙ*, we present necessary and sufficient conditions for oscillation...

Asymptotic properties of third order functional dynamic equations on time scales

I. Kubiaczyk; S. H. Saker — 2011

Annales Polonici Mathematici

The purpose of this paper is to study the asymptotic properties of nonoscillatory solutions of the third order nonlinear functional dynamic equation ${[p (t) {[{(r (t) x^{Δ} (t))}^{Δ}]}^{γ}]}^{Δ} + q (t) f (x (τ (t))) = 0$ , t ≥ t₀, on a time scale , where γ > 0 is a quotient of odd positive integers, and p, q, r and τ are positive right-dense continuous functions defined on . We classify the nonoscillatory solutions into certain classes $C_{i}$ , i = 0,1,2,3, according to the sign of the Δ-quasi-derivatives and obtain sufficient conditions in order that $C_{i} = \emptyset$ . Also, we establish...
