Asymptotic Behavior of Solutions of a Periodic Diffusion Equation

open access: yesJournal of Inequalities and Applications, 2010
We consider a degenerate parabolic equation with logistic periodic sources. First, we establish the existence of nontrivial nonnegative periodic solutions by monotonicity method. Then by using Moser iterative technique and the method of contradiction, we

On almost periodicity of solutions of second-order differential equations involving reflection of the argument

open access: yesAdvances in Difference Equations, 2019
We study almost periodic solutions for a class of nonlinear second-order differential equations involving reflection of the argument. We establish existence results of almost periodic solutions as critical points by a variational approach.

Periodic Peakon and Smooth Periodic Solutions for KP-MEW(3,2) Equation

open access: yesAdvances in Mathematical Physics, 2021
In this paper, we consider the KP-MEW(3,2) equation by the bifurcation theory of dynamical systems when integral constant is considered. The corresponding traveling wave system is a singular planar dynamical system with one singular straight line.

Large amplitude and multiple stable periodic oscillations in treatment-donation-stockpile dynamics

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
A transmission-treatment-donation-stockpile model was originally formulated for the 2014-2015 West Africa Ebola outbreak in order to inform policy complication of large scale use and collection of convalescent blood as an empiric treatment.

Stability and instability for periodic solutions of delay equations with "steplike" feedback

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
We consider the stability of periodic solutions of certain delay equations $x'(t) = f(x_t)$ for which the special structure of the equation allows us to define return maps that are semiconjugate to finite-dimensional maps.
