Tollmien, Schlichting, Lin et al. found that there exists a neutral curve, which consists of two branches: lower branch $\\alpha_{low}(Re)$ and upper branch $\\alpha_{up}(Re)$. Here, $\\alpha$ is the wave number and $Re$ is the Reynolds number. For any $\\alpha\\in(\\alpha_{low},\\alpha_{up})$, there exist unstable modes known as Tollmien-Schlichting (T-S) waves to the linearized Navier-Stokes system. These waves play a key role during the early stage of boundary layer transition.
