The Bargmann symmetry constraint and binary nonlinearization of the super Dirac systems
Jing Yu, Jingsong He, Wen-Xiu Ma +1
An explicit Bargmann symmetry constraint is computed and its associated binary nonlinearization of Lax pairs is carried out for the super Dirac systems. Under the obtained symmetry…

Direct search for exact solutions to the nonlinear Schroedinger equation
Wen-Xiu ma, Min Chen
A five-dimensional symmetry algebra consisting of Lie point symmetries is firstly computed for the nonlinear Schroedinger equation, which, together with a reflection invariance, ge…
