Abstract: The nonlinear agedependent population diffusion system was established. The existence of the generalized solution and that of the optimal control for the system were proved via the theory of partial differential equations combined with the delay method. The necessary conditions for the optimal control was given.

Key words: population diffusion system, generalized solution, ex istence, optimal control
