Multiple Equilibria in an Age-Structured Two-Sex Population Model
The complexity of age-structured two-sex population models has inhibited analysis of the uniqueness or stability of persistent distributions (i.e., equilibria in which the population grows exponentially with a fixed proportion in each age class). To offer some insight, this paper examines a special case in which couples dissolve only through the death of a spouse, and widows never remarry. Addi...
متن کاملPersistent Age Distributions for An Age-Structured Two-Sex Population Model∗
In this paper we formulate an age-structured two-sex population model which takes into account a monogamous marriage rule and the duration of marriage. We are mainly concerned with the existence of exponential solutions with a persistent age distribution. First we provide a semigroup method to deal with the time-evolution problem of our two-sex population model. Next, by constructing a fixed po...
متن کاملGenerating a Dynamic Synthetic Population – Using an Age-Structured Two-Sex Model for Household Dynamics
Generating a reliable computer-simulated synthetic population is necessary for knowledge processing and decision-making analysis in agent-based systems in order to measure, interpret and describe each target area and the human activity patterns within it. In this paper, both synthetic reconstruction (SR) and combinatorial optimisation (CO) techniques are discussed for generating a reliable synt...
متن کاملAsymptotic Behavior of an Age-structured Population Model with Diffusion
A reaction-diffusion system with stage-structure is studied. We provide well-posedness of the model and prove that time-dependent solutions evolve either towards a positive equilibrium or to the trivial one. Under suitable conditions, a branch of positive equilibrium is shown to exist.
