Cortés Vega", "A. Restuccia", "A. Sotomayor" ], "comment": "In this second version of 23 pages we obtain static solutions which play the role of a background for the system. We also discuss about the regularity of the solutions. We add some figures illustrating the solutions, including the one solitonic solution interacting with the static-background one. We modify the abstract in view of these improvements", "categories": [ "math-ph", "hep-th", "math.MP", "nlin.SI" ], "abstract": "We introduce a parametric coupled KdV system which contains, for particular values of the parameter, the complex extension of the KdV equation and one of the Hirota-Satsuma integrable systems. We obtain a generalized Gardner transformation and from the associated $\\varepsilon$- deformed system we get the infinite sequence of conserved quantities for the parametric coupled system. We also obtain a B\\\"{a}cklund transformation for the system. We prove the associated permutability theorem corresponding to such transformation and we generate new multi-solitonic and periodic solutions for the system depending on several parameters. We show that for a wide range of the parameters the solutions obtained from the permutability theorem are regular solutions. Finally we found new multisolitonic solutions propagating on a non-trivial regular static background.", "revisions": [ { "version": "v1", "updated": "2014-07-29T14:47:41.000Z", "abstract": "We obtain a B\\\"acklund transformation for a parametric coupled KdV system.
