| Abstract: | The nonlinear problem for the ptimal birth control of the time - verying population system is discussed, the existence of the optimal control is proved. The first order necessary condition for a control to be optimal is obtained. These results may provide a mathemtical theoretical basis for the practical research of the control problem in populations. |
