本文研究了二维空间单位球上拟地转方程在齐次Dirichlet边界条件下的Cauchy问题。在Besov空间的框架下证明了强解的存在唯一性。我们还建立了一个谱局部化技术和交换子估计。
We study the Cauchy problem for the quasi-geostrophic equations in a unit ball of the two-dimensional space with the homogeneous Dirichlet boundary condition. We show existence and uniqueness of the strong solution in the framework of Besov spaces. We also establish a spectral localization technique and commutator estimates.
