Global solutions of the 2D dissipative quasi-geostrophic equation in Besov spaces

The two-dimensional (2D) quasi-geostrophic (QG) equation is a 2D model of the 3D incompressible Euler equations, and its dissipative version includes an extra term bearing the operator $(-\Delta)^\alpha$ with $\alpha\in [0,1]$. Existing research appears to indicate the criticality of $\alpha=\frac12...
