A Hyperbolic Approximation of the Nonlinear Schrödinger Equation

Abhijit Biswas, Laila S. Busaleh, David I. Ketcheson +2

We study a first-order hyperbolic approximation of the nonlinear Schrödinger (NLS) equation. We show that the system is strictly hyperbolic and possesses a modified Hamiltonian str…
