摘要:
本文给出了几乎临界漂移-扩散方程在一般曲面上的活性标量的弱解的正则性结果。这包括各向异性非均匀介质的模型和二维球体的物理动机的情况。我们的最好结果处理了圆球上的临界面准地转方程。
英文摘要:
In this paper we provide regularity results for active scalars that are weak solutions of almost critical drift-diffusion equations in general surfaces. This includes models of anisotropic non-homogeneous media and the physically motivated case of the two-dimensional sphere. Our finest result deals with the critical surface quasigeostrophic equation on the round sphere.
