Discrete-time staged progression epidemic models
Luis Sanz-Lorenzo, Rafael Bravo de la Parra
In the Staged Progression (SP) epidemic models, infected individuals are classified into a suitable number of states. The goal of these models is to describe as closely as possible…
Non-linear population discrete models with two time scales: re-scaling of part of the slow process
Luis Sanz, Rafael Bravo de la Parra, Marcos Marvá +1
In this work we present a reduction result for discrete time systems with two time scales. In order to be valid, previous results in the field require some strong hypotheses that a…
A discrete model of competing species sharing a parasite
Rafael Bravo de La Parra, Luis Sanz
In this work we develop a discrete model of competing species affected by a common parasite. We analyze the influence of the fast development of the shared disease on the community…
Discrete epidemic models with two time scales
Luis Sanz-Lorenzo, Rafael Bravo de la Parra
The main aim of the work is to present a general class of two time scales discrete-time epidemic models. In the proposed framework the disease dynamics is considered to act on a sl…
Stochastic matrix metapopulation models with fast migration: re-scaling survival to the fast scale
Luis Sanz, Rafael Bravo de la Parra
In this work we address the analysis of discrete-time models of structured metapopulations subject to environmental stochasticity. Previous works on these models made use of the fa…
