The presented model is very useful but ...
this is a stochastic model. What about a population in equilibrium?? Equilibrium implies: Constant recruitment: Time-invariant exploitation rate: For the basic model therefore: Calculating the plus-group Building an age-structured model-I There are two fisheries with different vulnerabilities.

In this paper, we develop a rigourous mathematical analysis to study positive and negative effects of increased population density in the classical nonlinear age-structured population model introduced by Gurtin \\\& MacCamy in the late 1970s. One of our main results expresses the global stability...
In =-=[5]-=-, [12] are proposed numerical methods for the linear age-structured equation, i.e. with linear with respect to u(x, t) vital functionssand #:s= (a), # = #(a). The nonlinear age-structured model (withs...T.H. Barr: Approximation for age-structured population ...
•Two-state age-structured models popular in epidemiology of infectious diseases are considered.•Bayesian approach to data assimilation allowing us to calibrate structured population models with real word data is proposed.•In the case when the explicit solution to the model equation is known an...
In the first part of the volume, classical demographic models such as the stable population model and its linear extensions, density-dependent nonlinear models, and pair-formation models are formulated by the McKendrick partial differential equation and are analyzed from a dynamical system point of ...
