Periodic 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 کاملSome Simple Models for Nonlinear Age-Dependent Population Dynamics
This paper presents two simple models for nonlinear age-dependent population dynamics. In these models the basic equations of the theory reduce to systems of ordinary differential equations. We discuss certain qualitative aspects of these systems; in particular, we show that for many cases of interest periodic solutions are not possible. 1. BASIC EQUATIONS Recently, Gurtin and MacCamy [l] intro...
متن کاملMultiple Periodic Solutions for a First Order Nonlinear Functional Differential Equation with Applications to Population Dynamics
In this paper, we use Leggett-Williams multiple fixed point theorem to obtain several different sufficient conditions for the existence of at least three positive periodic solutions for the first order functional differential equations of the form y′(t) = −a(t)y(t) + λf(t, y(h(t))). Some applications to mathematical ecological models and population models are also given. AMS (MOS) Subject class...
