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 کاملA Note on the Convergence of the Homotopy Analysis Method for Nonlinear Age-Structured Population Models
In this paper, a theorem is proved which presents the series solution obtained from the homotopy analysis method is convergent to the exact solution of nonlinear age-structured population models.
متن کاملBifurcation Diagrams of Population Models with Nonlinear Diffusion
We develop analytical and numerical tools for the equilibrium solutions of a class of reaction-diffusion models with nonlinear diffusion rates. Such equations arise from population biology and material sciences. We obtain global bifurcation diagrams for various nonlinear diffusion functions and several growth rate functions.
متن کاملNonlinear Size - Structured Population Models A
In this dissertation, some size-structured population models are studied.In Chapter 1, a quasilinear size-structured model that describes the dynamics of apopulation with n competing ecotypes is studied. Under the assumption that the vitalrates of each subpopulation depend on the total population due to competition, theconditions on the individual rates which guarantee compe...
متن کاملsecuritization of mortality risks in life annuities
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
