Periodic solutions in a tumor-immune competition system with time-delay and chemotherapy effects
Pablo Amster, Andrés Rivera, John A. Arredondo
The main purpose of this paper is to analyze the dynamics of the system of time-delay differential equations (DDEs) \begin{equation*} \begin{split} \dot{T}(t)&=T(t) f(t,T(t))-γE(t)…

Persistence/extinction scenarios in an almost periodic metapopulation with competition and habitat destruction
Pablo Amster, Gonzalo Robledo, Daniel Sepúlveda
We study an almost periodic version of a metapopulation model developed by Tilman \textit{et.al} and Nee \textit{et.al} in the nineties, which generalizes the classical Levins appr…
