MW2: Perturbative techniques for integrable systems
Coordinator: Eugene Ferapontov (Loughborough University)
A useful point of view is to consider various classes of integrable equations as higher order perturbations of "simpler", or lower order equations. This includes such techniques as
- the theory of degenerate dispersion laws, which is a basis of the perturbative symmetry approach;
- dispersive deformations of equations of hydrodynamic type;
- the method of normal forms and asymptotic integrability, etc.
The aim of this mini-workshop is to review the current state of the art in this field.
