Positive Equilibrium Solutions for Age- and Spatially-Structured Population Models
نویسنده
چکیده
The existence of positive equilibrium solutions to age-dependent population equations with nonlinear diffusion is studied in an abstract setting. By introducing a bifurcation parameter measuring the intensity of the fertility it is shown that a branch of (positive) equilibria bifurcates from the trivial equilibrium. In some cases the direction of bifurcation is analyzed.

Global Bifurcation of Positive Equilibria in Nonlinear Population Models
Existence of nontrivial nonnegative equilibrium solutions for age structured population models with nonlinear diffusion is investigated. Introducing a parameter measuring the intensity of the fertility, global bifurcation is shown of a branch of positive equilibrium solutions emanating from the trivial equilibrium. Moreover, for the parameter-independent model we establish existence of positive...
متن کاملHopf Bifurcation for a Spatially and Age Structured Population Dynamics Model
This paper is devoted to the study of a spatially and age structured population dynamics model. We study the stability and Hopf bifurcation of the positive equilibrium of the model by using a bifurcation theory in the context of integrated semigroups. This problem is a first example for Hopf bifurcation for a spatially and age/size structured population dynamics model. Bifurcation analysis indi...

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.
متن کاملModels for Host-macroparasite Systems: a Comparison between Spatially Structured and Unstructured Models
We consider classical host-parasite systems consisting of ordinary differential equations for the total numbers of hosts, parasites,and larvae. We also consider a newer, spatially structured model that consists of a partial differential equation for each of those populations. We finally compare the behavior of solutions for the spatially homogeneous model to that of the solutions for the spatia...
