A nonlinear problem for age-structured population dynamics with spatial diffusion
Keywords
Density of age structured population, nonlinear parabolic problems, viscosity solutions, fixed point theoryAbstract
We consider a nonlinear model for age-dependent population dynamics subject to a density dependent factor which regulates the selection of newborn at age zero. The initial-boundary value problem is studied using a vanishing viscosity method (in the age direction) together with the fixed point theory. Existence and uniqueness are obtained, and also the positivity of the solution to the problem.Downloads
