报告题目:Fractals in Dynamical systems
报告摘要:
In this talk, some fundamental knowledge on Fractals geometry and dimension theory in Dynamical system is briefly introduced. We then give examples to show how to explore the orbit of some discrete dynamical systems in the view of fractal geometry.

报告题目:Traveling waves for reaction diffusion population models with spatio-temporal delays
报告摘要:
In this talk, I will introduce a class of reaction diffusion equation, which can be used to model some disease spread. Spreading speeds and uniqueness of traveling waves for the equation are systematically investigated. It is shown that there exists a spreading speed for this equation such that is linearly determinate and coincides with the minimal wave speed of traveling waves, and that this equation admits a unique traveling wave (up to translation) with speed and no traveling wave with .
