Almost Periodic Solution of a Discrete Schoener’s Competition Model with Delays

Almost Periodic Solutions of a Discrete Mutualism Model with Variable Delays

We discuss a discrete mutualism model with variable delays of the forms N1 n 1 N1 n exp{r1 n K1 n α1 n N2 n − μ2 n /1 N2 n − μ2 n − N1 n − ν1 n }, N2 n 1 N2 n exp{r2 n K2 n α2 n N1 n − μ1 n / 1 N1 n − μ1 n − N2 n − ν2 n }. By means of an almost periodic functional hull theory, sufficient conditions are established for the existence and uniqueness of globally attractive almost periodic solution ...

Permanence and existence of periodic solution of a discrete periodic Lotka–Volterra competition system with feedback control and time delays∗

Dynamics of almost periodic Schoener’s competition model with time delays and impulses

In real world, the ecological systems are usually perturbed by human exploitation activities such as planting and harvesting and so on. In order to obtain a more accurate description for such phenomenon, the impulsive differential equations play an important role. This paper is concerned with a kind of almost periodic Schoener's competition model with pure-delays and impulsive effects. By using...

Almost Periodic Solutions for Lasota-Wazewska Model with Multiple Delays

By means of Mawhin’s continuation theorem of coincidence degree theory, some new and simple sufficient conditions are obtained for the existence of at least one positive almost periodic solution for a class of delayed Lasota-Wazewska model with nonnegative coefficients. Further, by some important inequalities and Lyapunov functional, the permanence and global asymptotical stability of the model...

Joint influence of leakage delays and proportional delays on almost periodic solutions for FCNNs

This paper deals with fuzzy cellular neural networks (FCNNs) with leakage delays and proportional delays. Applying the differential inequality strategy, fixed point theorem and almost periodic function principle, some sufficient criteria which ensure the existence and global attractivity of a unique almost periodic solution for fuzzy cellular neuralnetworks with leakage delays and p...
