I will begin with presenting some developments on fractional Ornstein-Uhlenbeck processes, and define, as rigorously as possible, a stochastic evolution which stationary solution is irregular (in an Holder sense). This has very interesting applications in the modeling of the temporal structure of fluid turbulence. If I have enough time, I will then develop this idea in the context of the dynamics of the velocity gradient tensor, a work done in collaboration with R.M. Pereira (UERJ) and L. Moriconi (UFRJ). Come, it will be fun.
