*Scuola Normale Superiore*

(Aula Dini – Palazzo del Castelletto)
*Prof. Patrick Gérard*
*(Laboratoire de Mathématiques d'Orsay, **Université Paris-Sud, Orsay)*
Terrà un seminario dal titolo:
*“**Integrability versus wave turbulence for *
*Hamiltonian partial differential equations”*
*Abstract:*
In the world of Hamiltonian partial differential equations, complete
integrability and wave turbulence are often considered as opposite
paradigms. The purpose of this talk is first to give a rough idea of
these different notions. Then will be discussed the example of the
cubic Szegö equation, a nonlinear wave toy model which surprisingly
displays both properties. The key is a Lax pair structure involving
Hankel operators from classical analysis, and is connected to a
surprisingly explicit inverse spectral method.
