Abstract/Media

"This talk will be self-contained.

I will give the basic definitions related to the cubic Szegö equation and establish explicit formulae for the solutions with arbitrary initial data (not necessarily generic).

These formulae allow to prove the almost periodicity of every trajectory in the energy space H^{1/2}, in strong contrast with the turbulence phenomenon arising for higher Sobolev norms.

From joint works with Patrick Gérard, whose previous talks are not necessary to the understanding of this one... though they cannot harm.
