Stokes waves are periodic steady travelling water waves, which plays a fundamental role in the study of water waves (and ocean waves). It was surprised in 1967 that Benjamin and Feir observed that the Stokes waves are unstable under long wave perturbations (called modulational instability). However, the rigorous mathematical proof was missing for a long time. In this talk, I will discuss the first rigorous proof for the nonlinear modulational instability of the small amptitude Stokes waves in 2d water waves. This is joint work with Gong Chen.
