我们回顾了国家的最先进的一般生理结构人口模型的数学框架。当个体发展受到种群密度的影响时,这类模型将导致拟线性方程。我们展示了如何将一个动态系统(定义在无限维状态空间)与模型相关联,以及如何确定稳态。关于线性化稳定性的原理,我们提供了一个猜想,以及一些初步的步骤证明。
We review the state-of-the-art concerning a mathematical framework for general physiologically structured population models. When individual development is affected by the population density, such models lead to quasilinear equations. We show how to associate a dynamical system (defined on an infinite dimensional state space) to the model and how to determine the steady states. Concerning the principle of linearized stability, we offer a conjecture as well as some preliminary steps towards a proof.
