Abstract:
In this talk I would like to survey some recent results concerning
integrable partial differential equations (PDEs), a class of evolution
equations widely used in applications. Among the nonlinear integrable
PDEs, prominent examples are the nonlinear Schrödinger and the
Korteweg-de Vries equations.
I plan to discuss the method of normal forms, being one of the principal
tools to analyze them, in particular to describe their phase portraits
and to study perturbations of such equations.
