Hamiltonian Paradifferential Birkhoff Normal Form for Water Waves
2023, vol. 28, nos. 4-5, pp. 543-560

Abstract

We present the almost global in time existence result in [13] of small amplitude space periodic solutions of the 1D gravity-capillary water waves equations with constant vorticity and we describe the ideas of proof. This is based on a novel Hamiltonian paradifferential Birkhoff normal form approach for quasi-linear PDEs.

Keywords: water waves equations, vorticity, Hamiltonian Birkhoff normal form, paradifferential calculus
