Asymptotic Behavior of Solutions of a Periodic Diffusion Equation
Journal 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

Periodic Solutions and S-Asymptotically Periodic Solutions to Fractional Evolution Equations
Discrete Dynamics in Nature and Society, 2017 This paper deals with the existence and uniqueness of periodic solutions, S-asymptotically periodic solutions, and other types of bounded solutions for some fractional evolution equations with the Weyl-Liouville fractional derivative defined for periodic

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

Periodic Wave Solutions and Their Limits for the Generalized KP-BBM Equation
Journal of Applied Mathematics, 2012 We use the bifurcation method of dynamical systems to study the periodic wave solutions and their limits for the generalized KP-BBM equation. A number of explicit periodic wave solutions are obtained.

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

International Journal of Mathematics and Mathematical Sciences, 1990 In continuing from previous papers, where we studied the existence and uniqueness of the global solution and its asymptotic behavior as time t goes to infinity, we now search for a time-periodic weak solution u(t) for the equation whose weak formulation ...
