摘要
In this work, we show the existence and uniqueness, the analyticity of the solutions and the decay estimates of the solutions of the quasi-geostrophic equation (QG) in the Besov-Morrey spaces charterized by the semigroup T-alpha := e(-t(-triangle)alpha), noted by N-p,lambda(s). If we assume that the initial data theta 0 are small and belong to the Besov-Morrey critical spaces, we obtain the global well-posedness results of the QG equation.
