摘要 分析一类带有边界控制和迁移的非线性尺度结构种群模型。讨论了平衡态的存在唯一性,给出了平衡态的表达式,导出了系统的特征方程,获得了平衡解的稳定性条件。 This paper is concerned with a class of nonlinear size-structured population model with boundary control and immigration.We discuss the existence and uniqueness,derive the characteristic equation.Some results on the stability of the steady state of the system are established.
