Title
"Evolution of NLS with Bounded Data"
Avy Soffer- Rutgers University & Thomas Spencer- Institute for Advanced Study, Princeton
We study the nonlinear Schrodinger equation (NLS) with bounded initial data whichdoes not vanish at in finity. Examples include periodic, quasi-periodic and random initial data.On the lattice we prove that solutions are polynomially bounded in time for any bounded data. In the continuum, local existence is proved for real analytic data by a Newton iteration scheme. Global existence for NLS with a regularized nonlinearity follows by analyzing a local energy norm(arXiv:2003.08849 [math.AP]
