On the r-th dispersionless Toda hierarchy I: Factorization problem, symmetries and some solutions | | M. Manas

12 Apr 2004 | | Subject: | Exactly Solvable and Integrable Systems; Mathematical Physics; Analysis of PDEs | nlin.SI math-ph math.AP math.MP | | Abstract: | For a family of Poisson algebras, parametrized by by an integer number r, and an associated Lie algebraic splitting, we consider the factorization of given canonical transformations. In this context we rederive the recently found r-th dispersionless modified KP hierachies and r-th dispersionless Dym hierarchies, giving a new Miura map among them. We also found a new integrable hierarchy which we call the r-th dispersionless Toda hierarchy. Moreover, additional symmetries for these hierarchies are studied in detail and new symmetries depending on arbitrary functions are explicitly constructed for the r-th dispersionless KP, r-th dispersionless Dym and r-th dispersionless Toda equations. Some solutions are derived by examining the imposition of a time invariance to the potential r-th dispersionless Dym equation, for which a complete integral is presented and therefore an appropriate envelope leads to a general solution. Symmetries and Miura maps are applied to get new solutions and solutions of the r-th dispesionless modified KP equation. | | Source: | arXiv, nlin.SI/0404022 | | Services: | Forum | Review | PDF | Favorites | |
