研究一类带有Size结构竞争种群系统平衡解的稳定性条件.利用不动点定理证明了平衡解的存在唯一性,并得出了平衡解的特征方程.
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.
