- Title
On a System Modelling a Population with Two Age Groups.
- Authors
Hongliang Gao; Ruyun Ma
- Abstract
A system of first order ordinary differential equations describing a population divided into juvenile and adult age groups is studied. The system is not cooperative but its linear part is, and this makes it possible to establish the existence and nonexistence results of positive solutions for the system in terms of the principal eigenvalue of the corresponding linearized system.
