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…
Stability of a Delayed Predator-Prey Model for Puma Concolor
Wilson Mejías, Daniel Sepúlveda
This study presents a mathematical model that describes the relationship between the Puma concolor and its prey using delay differential equations, a Holling type III functional re…
Existence of periodic solution of Nicholson-type system with nonlinear density-dependent mortality
Gustavo Ossandón, Daniel Sepúlveda
This article studies an -periodic system of Nicholson-type differential equations with nonlinear density-dependent mortality rate. Using the degree theory we obtain sufficient c…
Approximation of Linear Differential Equations with variable delay on an Infinite Interval
Daniel Sepúlveda
We study approximation of non-autonomous linear differential equations with variable delay over infinite intervals. We use piecewise constant argument to obtain a corresponding dis…
Dichotomies and asymptotic equivalence in alternately advanced and delayed differential systems
Aníbal Coronel, Christopher Maulén, Manuel Pinto +1
In this paper, ordinary and exponential dichotomies are defined in differential equations with equations with piecewise constant argument of general type. We prove the asymptotic e…
