متن کاملPeriodic solution for a delay nonlinear population equation with feedback control and periodic external source
In this paper, sufficient conditions are investigated for the existence of periodic (not necessarily positive) solutions for nonlinear several time delay population system with feedback control. Nonlinear system affected by an periodic external source is studied. Existence of a control variable provides the extension of some previous results obtained in other studies. We give a illustrative e...
متن کاملPeriodic solutions for Nicholson-type delay system with nonlinear density-dependent mortality terms
This paper is concerned with the periodic solutions for a class of new Nicholson-type delay system with nonlinear density-dependent mortality terms. By using coincidence degree theory, some criteria are obtained to guarantee the existence of positive periodic solutions of the model. Moreover, an example is employed to illustrate the main results.
متن کاملGlobal attractivity of positive periodic solution to periodic Lotka – Volterra competition systems with pure delay ✩
We consider a periodic Lotka–Volterra competition system without instantaneous negative feedbacks (i.e., pure-delay systems) ẋi (t)= xi(t) [ ri (t)− n ∑ j=1 aij (t)xj ( t − τij (t) )] , i = 1,2, . . . , n. (∗) We establish some 3/2-type criteria for global attractivity of a positive periodic solution of the system, which generalize the well-known Wright’s 3/2 criteria for the autonomous delay l...
متن کاملExistence of Positive Periodic Solution of an Impulsive Delay SIS Model
In this paper, The impulsive delay epidemic SIS model is considered. By using the continuation theory for k-set contractions, the sufficient conditions of the existence of positive ω−periodic solutions of the impulsive delay SIS model are obtained.
