摘要：In an evolution model, the equilibrium states are the ones which do not depend on time. A constant equilibrium is often stable if the perturbation is also constant one, hence it is dynamically stable with respect to an ODE. More realistic models often include the effect of spatial movement. In this talk, we show that instability of a constant equilibrium can be caused by advection, diffusion, or chemotaxis. Moreover we show that Hopf bifurcations can occur in many cases so oscillatory states emerge.
