Since Reynolds’experiment in 1883, hydrodynamic stability has been an active field. This field focuses on how laminar flow becomes unstable and transit to turbulence. In order to understand the transition mechanism, Trefethen et al proposed the transition threshold problem. In this lecture, I will introduce some key ingredients of the proof for the stability threshold of the 2-D Couette flow and 3-D Couette flow.
