Symmetries for exact solutions to the nonlinear Schrödinger equation
Tuncay Aktosun, Theresa Busse, Francesco Demontis +1
A certain symmetry is exploited in expressing exact solutions to the focusing nonlinear Schrödinger equation in terms of a triplet of constant matrices. Consequently, for any numbe…
