Gibbs measures associated to the integrals of motion of the periodic derivative nonlinear Schrödinger equation
[OWP-2015-04] (Mathematisches Forschungsinstitut Oberwolfach, 2015-05-18)We study the one dimensional periodic derivative nonlinear Schrödinger (DNLS) equation. This is known to be a completely integrable system, in the sense that there is an infinite sequence of formal integrals of motion $\int ...
