| Abstract: | The stability conditions for the stationary solution of a two-species competitive size-structured population model is considered. The existence and uniqueness for the stationary solution are proved by means of fixed point theorem. The characteristic equation for the stationary solution is established by the knowledge of the ordinary differential equation. |

| Keywords: | size-structured stationary solution existence and uniqueness characteristic equation |
