Invariant measures and global well posedness for the SQG equation

J Földes, M Sy - Archive for Rational Mechanics and Analysis, 2021 - Springer
We construct an invariant measure μ for the Surface Quasi-Geostrophic (SQG) equation and
show that almost all functions in the support of μ are initial conditions of global, unique …
