Wave turbulence and asymptotic for singular integrals

Serguei Kuksin (UPMC)


I will discuss the stochastic model for the wave turbulence due
to Zakharov-L’vov, explain that the corresponding problem of decomposing
the energy spectrum to formal series in the properly scaled small
amplitude leads to asymptotic questions for a class of singular
integrals and show how to calculate this asymptotic. Finally I will
explain how these results allow to obtain the kinetic approximation for
the energy spectrum.
