Title: Bifurcation Theory and Its Application
Abstract: In this talk, we first briefly introduce some basic concepts of dynamical systems, such as stability, bifurcation, center manifold theory and normal form theory, and then focus on Hopf bifurcation. For application, we will present a deterministic in-host infection model to study viral blips (based on our SIGEST paper published in SIAM Review, 2014). This is the first time to give a complete dynamic analysis with a simple model for studying recurrent infection. Using bifurcation theory we propose a hypothesis consisting of four conditions for the existence of viral blips, revealing the basic mechanism of such phenomenon.
