报告摘要：Biologically, we are curious about the following question: How does the movement of individuals influence the persistence of a single population? A surprising phenomenon is that of dispersal-induced growth, whereby the population would become extinct if isolated, but dispersal, at an appropriate rate, can induce the persistence of the population. In this talk, we will discuss this topic based on a two-patch model and introduce the corresponding principal eigenvalue to explain such counter-intuitive effect of dispersal. The focus of this talk is on the applications of principal eigenvalue theory in population dynamics.
