Classification of integrable systems in 2D:deformation of dispersionless systems
Abstract:
The following approach to the classification integrable systems in 2+1 D
will be discussed:
1. First of all, one classifies dispersionless integrable systems based on
the method of hydrodynamic reductions;
2. Secondly, one constructs their dispersive deformations based on the
requirement that the dispersive system inherits deformations of all
hydrodynamic reductions of its dispersionless limit.
Examples illustrating this procedure will be considered.
