Sharp Strichartz estimates for water waves systems
Résumé
We prove for reasonably smooth solutions the optimal Strichartz estimates for pure gravity waves and the semi-classical Strichartz estimates for gravity-capillary waves; for both 2D and 3D waves. Here, by optimal we mean the gains of regularity obtained for the linearized systems. Our proofs combine the paradifferential reductions of Alazard-Burq-Zuily [1, 3] with a dispersive estimate using a localized wave package type parametrix of Koch-Tataru [19].
