【Abstract】 This paper discusses the problem of the optimal harvesting control problem for a semilinear age-dependent population diffusion system. It proves the existence of the optimal harvesting control, obtains the necessary condition for a control to be optimal, and then the optimality system consisting of integro-partial differential equations and variational inequlities, where the optimality system determines the optimal control.更多还原
