Generalizing the Levins metapopulation model to time varying colonization and extinction rates
Gonzalo Robledo, Ramiro Bustamante
The metapopulation theory explores the population persistence in fragmented habitats by considering a balance between the extinction of local populations and recolonization of empt…
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…
Uniform -dichotomies: noncritical uniformity and expansivity
Heli Elorreaga, Juan Peña, Gonzalo Robledo
The property of exponential dichotomy can be seen as a generalization of the hyperbolicity condition for non autonomous linear finite dimensional systems of ordinary differential e…
Criterion for exponential dichotomy of periodic generalized linear differential equations and an application to admissibility
Claudio A. Gallegos, Gonzalo Robledo
In this paper, we provide a necessary and sufficient condition ensuring the property of exponential dichotomy for periodic linear systems of generalized differential equations. Thi…
