Global attractivity for nonlinear differential equations with a nonlocal term

Electronic Journal of Differential Equations, 2014
In this article we analyze the dynamics of the problem $$\displaylines{ x'(t)=-(\delta+\beta(x(t)))x(t)+\theta\int_{0}^{\tau}f(a)x(t-a)\beta(x(t-a))da, \quad t> \tau, \cr x(t)=\phi(t),\quad 0 \leq t\leq \tau, }$$ where $\delta,\theta$ are ...

Almost periodic dynamics of a discrete Nicholson’s blowflies model involving a linear harvesting term

, 2012
We consider a discrete Nicholson’s blowflies model involving a linear harvesting term. Under appropriate assumptions, sufficient conditions are established for the existence and exponential convergence of positive almost periodic solutions of this model.

Strong resonance bifurcations of a discrete Nicholson′s blowf lies model with proportional delay

四川大学学报. 自然科学版
Population models have long been a focus of many researchers in the field of dynamical systems.Particularly， the discrete Nicholson’s blowﬂies model with proportional delay have attracted much attention due to its periodic oscillation.For the stability ...
