Aggregation in age and space structured population models: an asymptotic analysis approach

Aggregation in age and space structured population models: an asymptotic analysis approach In this paper we describe how techniques of asymptotic analysis can be used in a systematic way to perform ‘aggregation’ of variables, based on a separation of different time scales, in a population model with age and space structure. The main result of the paper is proving the convergence of the formal asymptotic expansion to the solution of the original equation. This result improves and clarifies earlier results of Arino et al. (SIAM J Appl Math 60(2):408–436, 1999 ), Auger et al. (Structured population models in biology and epidemiology. Springer Verlag, Berlin, 2008 ), Lisi and Totaro (Math Biosci 196(2):153–186, 2005 ). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Evolution Equations Springer Journals

Abstract

In this paper we describe how techniques of asymptotic analysis can be used in a systematic way to perform ‘aggregation’ of variables, based on a separation of different time scales, in a population model with age and space structure. The main result of the paper is proving the convergence of the formal asymptotic expansion to the solution of the original equation. This result improves and clarifies earlier results of Arino et al. (SIAM J Appl Math 60(2):408–436, 1999 ), Auger et al. (Structured population models in biology and epidemiology. Springer Verlag, Berlin, 2008 ), Lisi and Totaro (Math Biosci 196(2):153–186, 2005 ).
