Wave turbulence: a story far from over
Alan Newell (univ. Arizona)

30 juin 2007

Wave turbulence is the study of the long time statistical behavior of solutions to weakly nonlinear dispersive wave systems. Because it has a closed kinetic equation whose solutions capture both the equipartition and finite flux Kolmogorov solutions, the subject has often been consigned to the dustbin of solved problems. Story over, right? Wrong ! Wave turbulence is alive and well and has still lots of intellectual challenges. One set arises from the fact that wave turbulence is almost never uniformly valid over all scales. Another set of challenges arises from the anomolous way in which the Kolmogorov-Zakharov spectra are realized. I will briefly discuss these challenges.
