Variational methods for breather solutions of Nonlinear Wave Equations

Analysis of PDEs 2021-08-11 v3

Abstract

We construct infinitely many real-valued, time-periodic breather solutions of power-type nonlinear wave equations. These solutions are obtained from critical points of a dual functional and they are weakly localized in space. Our abstract framework allows to find similar existence results for the Klein-Gordon equation or biharmonic wave equations.
