Transient and asymptotic dynamics of some nonlinear evolution equations from ecological modeling and epidemiological modeling will be studied in this proposed research. For ecological systems, this proposal mainly concerns the interplay of competition and predation. An emphasis will be placed on intra-guild predation involving three species, predator-prey (plant-herbivore) systems with spatial heterogeneities and stochasticity. For epidemiological systems, the proposal focuses on modeling the transmission and control of infectious diseases. In particular, two broad problems will be investigated: interactions of cells, pathogens and immune responses within a host, and adaptive dispersal of a population between patches.

在这项拟议的研究中，将研究来自生态建模和流行病学建模的某些非线性演化方程的瞬时和渐近动力学。对于生态系统，该建议主要涉及竞争与捕食的相互作用。将重点放在涉及三个物种的捕食捕食上，即具有空间异质性和随机性的三种物种，即捕食者捕食者（植物 - 纯种）系统。对于流行病学系统，该提案着重于建模传染病的传播和控制。特别是，将研究两个广泛的问题：宿主内细胞，病原体和免疫反应的相互作用，以及斑块之间人群的适应性分散。
