From nonassociativity to solutions of the KP hierarchy | Aristophanes Dimakis

10 Aug 2006 | Abstract: | A recently observed relation between ’weakly nonassociative’ algebras A (for which the associator (A,A^2,A) vanishes) and the KP hierarchy (with dependent variable in the middle nucleus A’ of A) is recalled. For any such algebra there is a nonassociative hierarchy of ODEs, the solutions of which determine solutions of the KP hierarchy. In a special case, and with A’ a matrix algebra, this becomes a matrix Riccati hierarchy which is easily solved. The matrix solution then leads to solutions of the scalar KP hierarchy. We discuss some classes of solutions obtained in this way. | Source: | arXiv, nlin/0608017 | Services: | Forum | Review | PDF | Favorites |
