"We have previously, in joint work with Jerry Bona, David Nicholls, and Michael Siegel, demonstrated that truncated series models of gravity water waves exhibit ill-posedness. In joint work with Shunlian Liu, we show that the addition of sufficiently strong dispersion makes such a system well-posed. Physically, this strong dispersion can be relevant, for instance, for hydroelastic waves. The proof uses techniques of paradifferential calculus."@en .
