| Abstract: | In this article,we investigate the exact controllability of a class of population model.By using Carleman estimates for the linearized equation and Kakutani fixed point theorem,we establish the local controllability of steady state solutions to this model.The results fully reflect the influence action of external control in evolution of population. |
