摘要:

该文借助于线性算子理论,探讨了以细菌种群为背景的具结构化的更一般的边界条件的迁移方程, 运用预解算子和比较算子等方法证明了该迁移方程相应迁移算子谱在带域$\Gamma_{\alpha, \beta}$中仅由有限个具有限代数重数的离散本征值构成, 证明了该迁移方程解在$\psi_0 \in D (A_{H_{\alpha, \beta}})$时是渐近稳定的.

关键词: 细菌种群, 迁移方程, 离散本征值, 渐近稳定性

Abstract:

With the help of linear operator theory, the transport equation with more general boundary condition for the structured equation with bacterial population as background is discussed. By means of resolving operator and comparison operator, it is proved that the corresponding transfer operator spectrum of the transfer equation consists of only a finite number of discrete eigenvalues with finite algebraic multiplicity in band domain $\Gamma_{\alpha, \beta}$. It is proved that the solution of the transfer equation is asymptotically stable when $\psi_0 \in D (A_{H_{\alpha, \beta}})$.

Key words: Bacterial population, Transport equation, Discrete eigenvalues, Asymptotic stability
