Integration of the Loaded Negative Order Nonlinear Schrodinger Equation in the Class of Periodic Functions [PDF]
Известия Иркутского государственного университета: Серия "Математика"In this paper, we consider the loaded negative order nonlinear Schrodinger equation (NSE) in the class of periodic functions. It is shown that the loaded negative order nonlinear Schrodinger equation can be integrated by the inverse spectral problem ...
