研究一个带分布时滞的具有尺度结构的种群模型。此模型将个体分为“活跃”期和“休眠”期两个阶段研究。利用算子半群的理论证明了此模型的适定性并证明此模型的解具有平衡指数增长的性质。
A size-structured two-phase population model with delayed birth process is studied. The wellposedness for this model is established. It is shown that the solution of this model has balanced exponential growth by means of semigroups.
