Existence of positive periodic solution of a periodic cooperative model with delays and impulses
where ai, bi, and ci (i= 1,2) are nonnegative ω-periodic continuous functions. It is well known that more realistic and interesting species models should take into account both the seasonality of the changing environment and time delays [4, 8, 9], and that the birth of many species is not continuous but occurs at fixed time intervals (some wild animals have seasonal births), in the long run; th...
متن کاملExistence and uniqueness of periodic solution for a discrete-time SIR epidemic model with time delays and impulses
In this paper, a discrete-time SIR epidemic model with nonlinear incidence rate, time delays and impulses is investigated. Sufficient conditions for the existence and uniqueness of periodic solutions are obtained by using contraction theorem and inequality techniques. An example is employed to illustrate our results. Keywords—Discrete-time SIR epidemic model, Time delay, Nonlinear incidence rat...
متن کاملThe existence of positive periodic solutions for periodic feedback control systems with delays
where τ, δ, a, b, c, r, k ∈ C(R, (0,∞)) are ω-periodic functions. The assumption of periodicity of the parameters a(t), b(t), c(t), k(t), r(t) is a way of incorporating the periodicity of the environment (e.g. seasonal effects of weather condition, food supplies, temperature, etc.). The main purpose of this paper is to establish the existence of a positive periodic solution of system (2), using...
متن کاملExistence and Exponential Stability of Almost Periodic Solution for Shunting Inhibitory Cellular Neural Networks with Distributed Delays and Large Impulses
This paper considers the problem of existence and exponential stability of almost periodic solution for shunting inhibitory cellular neural networks with distributed delays and large impulses. Based on the contraction principle and Gronwall-Bellman’s inequality, some sufficient conditions are obtained. The results of this paper are new and they complement previously known results.
متن کاملExistence of Almost Periodic Solutions for Hopfield Neural Networks with Continuously Distributed Delays and Impulses
By means of a Cauchy matrix, we prove the existence of almost periodic solutions for Hopfield neural networks with continuously distributed delays and impulses. An example is employed to illustrate our results.
