Abstract
We present a regularity result for weak solutions of the 2D quasi-geostrophic equation with supercritical (α < 1 / 2) dissipation (- Δ)α: If a Leray-Hopf weak solution is Hölder continuous θ ∈ Cδ (R2) with δ > 1 - 2 α on the time interval [t0, t], then it is actually a classical solution on (t0, t].
