Periodic traveling wave solutions of the Nicholson's blowflies model with delay and advection

open access: yesElectronic Research Archive, 2023
The existence, stability and bifurcation direction of periodic traveling waves for the Nicholson's blowflies model with delay and advection are investigated by applying the Hopf bifurcation theorem, center manifold theorem as well as normal form theory ...

New results on almost periodic solutions for a Nicholson's blowflies model with a linear harvesting term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper, we study the global dynamic behavior of a non-autonomous delayed Nicholson's blowflies model with a linear harvesting term. Under proper conditions, we employ a novel argument to establish a criterion on the global exponential stability of

Convergence of solutions of nonautonomous Nicholson's Blowflies model with impulses

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2019
Summary: This paper deals with a nonautonomous Nicholson's blowflies model with impulses. It is shown that under the proper conditions every positive solution of the model approaches to a constant as \(t\) tends to infinity.

Analysis of Stochastic Nicholson‐Type Delay System under Markovian Switching on Patches

open access: yesComplexity, Volume 2020, Issue 1, 2020., 2020
Based on the influence of random environmental perturbations and the patch structure, we propose a stochastic Nicholson‐type delay system under Markovian switching on patches. Existence of a global positive solution is studied. Then, we show ultimate boundedness and estimation of the sample Lyapunov exponent of the solution.

On the Stability and Uniform Persistence of a Discrete Model of Nicholson′s Blowflies

open access: yesJournal of Mathematical Analysis and Applications, 1995
The authors study the behaviour of nonnegative solutions to the difference equation \[ N_{k+ 1}- N_k= - \delta N_k+ pN_{k- i} e^{- aN_{k- i}},\tag{1} \] where \(k\in \mathbb{N}\cup 0\), \(N_i\geq 0\), \(\delta\), \(a\), \(p\) are positive constants. This equation is the discrete analogue of some delay differential equation used to model the dynamics of

Periodic Travelling Waves of the Delayed Nicholson’s Blowflies Model with Diffusion

open access: yes, 2023
In this paper, we investigate the existence of periodic travelling waves with large wave speed for the diffusion Nicholson’s blowflies model with delay effect by applying the perturbation technique. The proof depends on transforming the differential equation with the wave profile into integral equation, combining the implicit function theorem and the ...

Global Attractivity of a Diffusive Nicholson's Blowflies Equation with Multiple Delays

open access: yesAbstract and Applied Analysis, 2013
The present paper considers a diffusive Nicholson's blowflies model with multiple delays under a Neumann boundary condition. Delay independent conditions are derived for the global attractivity of the trivial equilibrium and the positive equilibrium ...
