| Abstract: | In this paper we consider the 2D dissipative quasi-geostrophic equations and study the regularity criterion of the solutions. By means of a commutator estimate based on frequency localization and Bony's paraproduct decomposition, we obtain a regularity criterion |
| Keywords: | Frequency localization Commutator estimate Littlewood-Paley decomposition Regularity criterion Quasi-geostrophic equation |
