Approximate controllability of population dynamics with size dependence and spatial distribution

Shu-Ping Wang, Ze-Rong He


We investigate the approximate controllability of a size- and space-structured population model, for which the control function acts on a subdomain and corresponds to the migration of individuals. We establish the main result via the unique continuation property of the adjoint system. The desired controller is the minimizer of an infinite-dimensional optimization problem.
