摘要
考虑一类具有Size结构的非线性种群系统平衡解的稳定性条件.利用不动点定理得到了平衡态的存在唯一性,给出平衡态的表达式,导出了系统的特征方程,从而获得平衡解的稳定性条件.
The stability for stationary solution of a nonlinear size-structured population is studied. The existence and unique ness of the stationary solution is obtained by using fixed point theorem. The expression of the stationary solution is given. The characteristic equation is derived and the stability conditions are obtained.
