Global well-posedness for the critical 2D dissipative quasi-geostrophic equation

arXiv:math/0604185 · doi:10.1007/s00222-006-0020-3

Abstract

We give an elementary proof of the global well-posedness for the critical 2D dissipative quasi-geostrophic equation. The argument is based on a non-local maximum principle involving appropriate moduli of continuity.
