a) quantum physics, where “one particle” NLS occur as approximate models for the linear N-body Schrödinger equation. Quantum HydroDynamics

b) nonlinear optics, where the paraxial approximation of the Helmholtz (wave) equation yields 2+1 dimensional cubic NLS2) Analysis:

Existence and Uniqueness (“Local/global WellPosedness) of NLS and NLW with local and non-local nonlinearity, scattering, finite(-time) Blow-up;
