26 Apr 2001 | Subject: | Exactly Solvable and Integrable Systems | nlin.SI | Abstract: | We present the constraint for the discrete Moutard equation which gives the integrable discretization of the Bianchi-Ernst system. We also derive the discrete analogue of the Bianchi transformation between solutions of such a system (the Darboux-Backlund transformation in soliton terminology). We finally obtain the superposition of discrete Bianchi transformations. | Source: | arXiv, nlin.SI/0104065 | Services: | Forum | Review | PDF | Favorites |
