Darboux Transformation for Drinfel'd-Sokolov-Wilson Equation |
|
| Abstract: | A coupled system known as tie Drinfel'd-Sokolov-Wilson equation is reexamined.With the help of a Lax operator of fourth order,its proper Darboux transformation is constructed.Also,a nonlinear superposition formula is worked out for the associated Backlund transformation and some solutions are calculated. |
