Oscillation of partial population model with diffusion and delay
نویسندگان
چکیده
By using the upperand lower-solution method of partial functional differential equations and the oscillation theory of functional differential equation, the oscillation of a population equation with diffusion and delay is studied and a sufficient condition for all positive solutions of the equation to oscillate about the positive equilibrium is obtained. Finally, a model arising from ecology is given to illustrate the obtained results. © 2009 Elsevier Ltd. All rights reserved.

Nonlinear oscillation of certain third-order neutral differential equation with distributed delay
The authors obtain necessary and sufficient conditions for the existence of oscillatory solutions with a specified asymptotic behavior of solutions to a nonlinear neutral differential equation with distributed delay of third order. We give new theorems which ensure that every solution to be either oscillatory or converges to zero asymptotically. Examples dwelling upon the importance of applicab...
متن کاملOscillation Criteria of Impulsive Neutral Parabolic Equations with Nonlinear Diffusion Coefficient
In 1991, the first paper on impulsive partial differential equations [1] was published. For an excellent exposition of this paper and its applications, see [2]. The oscillation theory of impulsive partial differential equations have wide applications in such subjects as control theory, meteorology, biology, medicine, engineering, chemistry and physics. Many results can be found [3-14]. However,...
متن کاملOscillation for Nonlinear Hyperbolic Equations with Influence of Impulse and Delay
In this paper, by making use of the calculous technique and some results of the differential inequality, oscillatory properties of the solutions of certain impulsive delay hyperbolic partial differential equations with nonlinear diffusion term are investigated. A new sufficient criterion for oscillations of such equations is obtained.
متن کاملA theory of synchrony for active compartments with delays coupled through bulk diffusion
We extend recent work on the analysis of synchronization in a pair of biochemical oscillators coupled by linear bulk diffusion, in order to explore the effects of discrete delays. More specifically, we consider two well-mixed, identical compartments located at either end of a bounded, one-dimensional domain. The compartments can exchange signaling molecules with the bulk domain, within which th...
متن کاملHopf bifurcations in a reaction–diffusion population model with delay effect
A reaction-diffusion population model with a general time-delayed growth rate per capita is considered. From a careful analysis of the characteristic equation, the stability of the positive steady state solution and the existence of supercritical Hopf bifurcation from the positive steady state solution are obtained via the implicit function theorem, where the time delay is used as the bifurcati...
