Abstract: | We study the two dimensional dissipative quasi-geostrophic equations in the Sobolev space Existence and uniqueness of the solution local in time is proved in Hs when s>2(1–). Existence and uniqueness of the solution global in time is also proved in Hs when s2(1–) and the initial data is small. For the case, s>2(1–), we also obtain the unique large global solution in Hs provided that is small enough.Acknowledgement The author thanks Professor Jiahong Wu for useful conversations, Professor Antonio Cordoba for kindly providing their preprints and Professor Peter Constantin for kind suggestions and encouragement.
