Our goal in this volume is to apply a normal forms method to estimate the Sobolev norms of the solutions of the water waves equation. We construct a paradifferential change of unknown, without derivatives losses, which eliminates the part of the quadratic terms that bring non zero contributions in a

This book examines the Cauchy problem for elliptic equations under the aspects of approximation, solvability, and reconstruction of solutions via their initial data. It also explores the problem of analytic continuation of functions from a boundary subset.
