Deformations of bihamiltonian structures of hydrodynamic type
Paolo Lorenzoni ;
Date 9 Aug 2001
Subject Exactly Solvable and Integrable Systems; Pattern Formation and Solitons; Differential Geometry | nlin.SI math.DG nlin.PS
AbstractIn this paper we study the deformations of bihamiltonian PDEs of hydrodynamic type with one dependent variable. The reason we study such deformations is that the deformed systems maintain an infinite number of commuting integrals of motion up to a certain order in the deformation parameter. This fact suggests that these systems could have, at least for small times, multi-solitons solutions. Our numerical experiments confirm this hypothesis.
