THE WELL POSEDNESS OF THE TIME-DEPENDENT POPULATION DANAMICS SYSTEM AND THE OPTIMAL CONTROL ON THE FERTILITY RATE
时变人口系统的适定性及关于生育率的最优控制

In this paper, we discuss the wellposedness of the time-dependent population system and the optimal control on the fertility rate by using the functional analysis methods and Liyapunov function methods. The population system is wellposed and the optimal fertility rate is obtained.
