Existence and Stability of Periodic Solution Related to Valveless Pumping

open access: yesMathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
Valveless pumping, also known as Liebau effect, can be described as the unidirectional flow of liquid in a system without valves that is caused by the asymmetry of placing of the periodically working pump. Recently, the research in this field has been reevoked, partially due to its possible application in nanotechnologies.

Population Growth in Space and Time [PDF]

open access: yes, 2003
How great an effect does self-generated spatial structure have on logistic population growth? Results are described from an individual based model (IBM) with spatially localized dispersal and competition, and from a deterministic approximation to the IBM

Global Stability of Traveling Waves for a More General Nonlocal Reaction‐Diffusion Equation

open access: yesDiscrete Dynamics in Nature and Society, Volume 2018, Issue 1, 2018., 2018
The purpose of this paper is to investigate the global stability of traveling front solutions with noncritical and critical speeds for a more general nonlocal reaction‐diffusion equation with or without delay. Our analysis relies on the technical weighted energy method and Fourier transform.

Oscillation Conditions for Difference Equations with a Monotone or Nonmonotone Argument

open access: yesDiscrete Dynamics in Nature and Society, Volume 2018, Issue 1, 2018., 2018
Consider the first‐order delay difference equation with a constant argument Δx(n) + p(n)x(n − k) = 0, n = 0,1, 2, …, and the delay difference equation with a variable argument Δx(n) + p(n)x(τ(n)) = 0, n = 0,1, 2, …, where p(n) is a sequence of nonnegative real numbers, k is a positive integer, Δx(n) = x(n + 1) − x(n), and τ(n) is a sequence of integers

Oscillation and global attractivity in a periodic Nicholson's blowflies model

open access: yesMathematical and Computer Modelling, 2002
Here, the authors consider the following nonlinear delay differential equation \[ N'(t)=-\delta N(t)+P(t)N(t-m\omega)e^{-\alpha N(t-n\omega)},\tag{*} \] where \(m\) is a positive integer, \(\delta(t)\) and \(P(t)\) are positive \(\omega\)-periodic functions.

Periodic solutions for a class of diffusive Nicholson’s blowflies model with Dirichlet boundary conditions [PDF]

open access: yesJournal of Inequalities and Applications, 2013
Abstract In this paper, we study the problem of periodic solutions for a class of diffusive Nicholson’s blowflies model with Dirichlet boundary conditions. By applying the Schauder fixed point theorem, the existence of nontrivial nonnegative periodic solutions of the considered model is established.
