Outline of Final Research Achievements |
Ordered structures are widely observed for long term in turbulence, e.g., the great red spot on Jupiter. It has been known that in the two dimensional flow, this phenomena is due to the quasi-equilibria and equilibria arising in the mean field of many point vortices, while there is a recursive hierarchy through the particles and their mean field. This project is a fusion of nonlinear analysis and non- equilibrium statistical mechanics. We have rigorously proven the recursive hierarchy in the dynamical level, and also derived a mathematical model for the point vortex mean field in the relaxation time compatible to the patch and equilibrium models.
