考虑具有耗散项κ(-Δ)αθ的准地转方程, 的情况下 Constantin-Cordoba-Wu [6]在初始值的L ∞范数较小的假设下证明了H1和H2中强解的整体存在性.本文证明了标度不变Besov空间B2−2α 2,1中的整体存在性, 对于在B2 −2α 2,1范数下很小的初始数据。我们还证明了B12,1的一个全局稳定性结果。
We consider the quasi-geostrophic equation with the dissipation term, κ (-Δ)αθ, In the case , Constantin-Cordoba-Wu [6] proved the global existence of strong solution inH1andH2under the assumption of smallL∞-norm of initial data. In this paper, we prove the global existence in the scale invariant Besov space,B2−2α2,1, for initial data small in theB2−2α2,1norm. We also prove a global stability result inB12,1.
