Asymptotic Behaviour for a Nonlinear Age-structured Population Model with Diffusion∗ By
نویسنده
چکیده
The internal zero-stabilization of the nonnegative solution to a nonlinear age-dependent population model with diffusion is investigated in this paper. It is provided here a necessary condition and a sufficient condition for the nonnegative zerostabilizability in terms of the value of the principal eigenvalue to a certain elliptic operator. This principal eigenvalue is related to the rate of the convergence of the solution. Mathematics Subject Classification 2000: 35B37.

Superlinearly convergent exact penalty projected structured Hessian updating schemes for constrained nonlinear least squares: asymptotic analysis
We present a structured algorithm for solving constrained nonlinear least squares problems, and establish its local two-step Q-superlinear convergence. The approach is based on an adaptive structured scheme due to Mahdavi-Amiri and Bartels of the exact penalty method of Coleman and Conn for nonlinearly constrained optimization problems. The structured adaptation also makes use of the ideas of N...

متن کاملNonlinear analytical solution of nearly incompressible hyperelastic cylinder with variable thickness under non-uniform pressure by perturbation technique
In this paper, nonlinear analytical solution of pressurized thick cylindrical shells with variable thickness made of hyperelastic materials is presented. The governing equilibrium equations for the cylindrical shell with variable thickness under non-uniform internal pressure are derived based on first-order shear deformation theory (FSDT). The shell is assumed to be made of isotropic and homoge...
متن کاملAsymptotic Analysis of a Semelparous Species Model
We study a non-linear age-structured discrete-time population model and give necessary and sufficient conditions for stability of a positive stationary point. In the case of semelparous species we show that the population converges locally to a population consisted only of individuals at one age. It means that the long-time behaviour of the population depends only on an one-dimensional transfor...
متن کاملDynamical behavior of a stage structured prey-predator model
In this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. The stages for prey have been considered. The proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. The model is analyzed by using linear stability analysis to ob...
